    OPINION
    _________________
    CHAD A. READLER, Circuit Judge. Methamphetamine may not be manufactured
    without governmental authorization. 21 U.S.C. § 841(a)(1); 21 U.S.C. § 843(a)(6). Congress
    has regulated this practice in part to curb the unauthorized distribution of methamphetamine,
    which has a “detrimental effect on [our] health and general welfare.” 21 U.S.C. § 801(2). Yet
    equally detrimental, in many respects, is the process for manufacturing methamphetamine, which
    itself can have potentially hazardous consequences, if not done under appropriate conditions.
    See Hazards Of Illicit Methamphetamine Production And Efforts At Reduction: Data From The
    Hazardous Substances Emergency Events Surveillance System, U.S. Dept. Health and Human
    Services, Public Health Reports 126 (supp. 1), 121–22 (2011). As the “illegal production of
    meth[amphetamine] often involves use of volatile chemicals and makeshift equipment, these
    sites can be extremely dangerous.” 
    Id. Among the
    dangers is the risk that, during and after the
    manufacturing process, the ingredients and equipment will explode or otherwise catch fire. 
    Id. Reflecting those
    concerns, the Sentencing Guidelines impose a sentencing enhancement
    on one who, in illegally manufacturing methamphetamine, creates a risk of harm to others.
    U.S.S.G. § 2D1.1(b)(14)(C).      That enhancement is especially potent when a defendant’s
    manufacturing presented “a substantial risk of harm to the life of a minor.”             U.S.S.G.
    § 2D1.1(b)(14)(D) (emphasis added).       Crafting that Guidelines section was one thing, but
    applying it can be quite another. After all, given the various ways in which illegal
    methamphetamine manufacturing takes place, courts often have some interpretative work to do
    in assessing whether the conduct at issue rises to the level of creating a “substantial risk to the
    life of a minor.” In our mind, two principal considerations help inform whether a defendant’s
    manufacturing satisfies the “substantial risk” threshold: (1) the likelihood the conduct at issue
    risks harm to a minor; and (2) how serious that harm might be, should the risk come to pass.
    No. 18-5736                          United States v. Owen                                 Page 3
    We are asked to apply those considerations to a defendant who, while riding in a vehicle
    with a seven-year-old child, transported equipment that had been used to manufacture
    methamphetamine. In that setting, the equipment presented a modest risk of combustion, and
    thus a modest risk of injuring the minor. By the same token, any combustion would have been
    devastating to the minor, if not fatal. In this close case, we agree with the district court that, on
    balance, the likelihood of substantial injury to the child in the vehicle should the equipment
    combust constitutes a “substantial risk of harm to the life of a minor.”           We accordingly
    AFFIRM the judgment of the district court.
    I. FACTS AND PROCEDURAL HISTORY
    Officer Ryan Patterson stopped a vehicle with four passengers, one of whom was seven
    years old. Another passenger, defendant Michael Owen, exited the vehicle while holding a black
    bag, and attempted to flee. Patterson gave chase. When he did, Owen returned to the vehicle
    and retrieved a short-barreled shotgun. He then fired at Patterson. Simultaneously, Patterson,
    who was not hit by Owen’s shot, tased Owen. Owen dropped the shotgun and attempted to flee
    to a wooded area. At some point during his attempted flight, Owen also dropped the bag he was
    carrying. Ultimately, Patterson detained and arrested Owen, and recovered the bag.
    Following an initial search of the bag, officers called in Officer Ryan Wilkey, who was
    trained in methamphetamine investigations. From the contents in the bag, Wilkey identified a
    clear plastic bottle containing “white sludge” covered with a copper-colored film. He also found
    lighter fluid, tubing, coffee filters, lithium batteries, a white powder, and a container of white
    pellets. Recognizing the dangers this collection of items presented, Wilkey moved the bottle
    away from the other chemicals, and then unscrewed the bottle’s cap to release any pressure.
    A methamphetamine task force was later called in to neutralize and dismantle the remaining
    items. The task force then pH tested several chemicals, and discovered both strong acids and
    bases.
    No. 18-5736                         United States v. Owen                                  Page 4
    For this conduct, Owen was indicted and charged with six counts:
    •   Count One, attempt to manufacture methamphetamine, in violation of
    21 U.S.C. §§ 841(a)(1), (b)(1)(C), & 846.
    •   Count Two, possession of equipment, chemicals, products, and materials
    that may be used in the manufacture of methamphetamine, in violation of
    21 U.S.C. § 843(a)(6).
    •   Count Three, using, carrying, and discharging a firearm in relation to the
    drug trafficking crimes alleged in Counts One and Two, in violation of
    18 U.S.C. § 924(c)(1)(A)
    •   Count Four, possessing and discharging a firearm during and in
    furtherance of the drug trafficking offenses charged in Counts One and
    Two, in violation of 18 U.S.C. § 924(c)(1)(A).
    •   Count Five, being a felon in possession of a firearm and ammunition, in
    violation of 18 U.S.C. §§ 922(g)(1) & 924(a)(2).
    •   Count Six, possession of an unregistered firearm, in violation of 26 U.S.C.
    §§ 5845(a), 5861(d), & 5871.
    Owen subsequently pleaded guilty to Counts One (attempt to manufacture methamphetamine)
    and Three (discharging a firearm in furtherance of a drug offense) of the indictment. Per the plea
    agreement, the district court dismissed the remaining counts.
    Before his guilty plea, Owen filed various motions for psychological examinations,
    which the district court granted. Owen later filed a motion for a competency hearing. The
    district court held a hearing and, almost five years after Owen was indicted, found him
    competent to stand trial, at which point Owen pleaded guilty to the two counts.
    The presentence report (or “PSR”) set Owen’s base offense level at 12. Owen’s offense
    level was increased pursuant to § 2D1.1(b)(14)(D) of the Sentencing Guidelines on the grounds
    that Owen’s methamphetamine-manufacturing offense created a “substantial risk of harm to the
    life of a minor.” Where a defendant’s conduct qualifies for that enhancement, the defendant’s
    offense level is increased by six levels, or raised to an offense level of 30, whichever is greater.
    Owen’s offense level was thus raised to 30, and then adjusted downward three levels, to 27, for
    accepting responsibility for his crimes. Owen was also deemed to have had a criminal history
    category of VI.
    No. 18-5736                         United States v. Owen                                 Page 5
    As calculated in the PSR, the Sentencing Guidelines range for an offense level of 27 with
    a criminal history category of VI was 130 to 162 months. Because Owen discharged a firearm,
    he was subject to a 120-month mandatory minimum sentence pursuant to 18 U.S.C.
    § 924(c)(1)(A). As a result, Owen’s sentencing range was 250 to 282 months of imprisonment.
    At Owen’s sentencing hearing, the parties took up Owen’s enhancement for creating
    “a substantial risk of harm to the life of a minor.” U.S.S.G. § 2D1.1(b)(14)(D). To support the
    sentencing enhancement, the government called two witnesses:            Wilkey and Agent David
    Shelton of the Tennessee Bureau of Investigation Dangerous Drug Task Force.
    Wilkey testified that the bag carried by Owen contained equipment and chemicals used
    for the manufacture of methamphetamine, including a one-pot shake bottle. But Wilkey added
    little more. For instance, he testified that the one-pot did not appear to contain an ongoing
    reaction and that he did not smell the odor normally associated with one-pot cooking of
    methamphetamine.
    Shelton filled in many of the gaps. Shelton first explained the process for manufacturing
    methamphetamine. Turning to the items in Owen’s bag, Shelton testified that the chemical
    reactions that took place in the one-pot had finished and that the methamphetamine had been
    removed prior to the one-pot being seized by law enforcement. And although he did not see
    lighter fluid and water in the bottle, Shelton, based on his experience and training, testified that
    those items had to be in the bottle, as he had never known a methamphetamine cook able to
    remove all the fluids. Much the same was true, Shelton testified, with respect to unreacted
    lithium. Here again, while Shelton could not see any lithium in the photographs of the one-pot,
    and while no laboratory testing was completed to produce evidence of unreacted lithium, he
    testified that he had never seen a one-pot in which there was no unreacted lithium. Shelton
    further testified that the chemicals found in the bag were hazardous: they were not in their
    original containers, were flammable, and could “cause chemical burns” by “eating your skin.”
    There was thus a “distinct possibility,” Shelton concluded, that the contents of the bottle could
    create a fire.
    No. 18-5736                          United States v. Owen                                Page 6
    Taking all of this into account, the district court was left to determine whether Owen’s
    methamphetamine-manufacturing conduct “create[d] a substantial risk of harm to the life of a
    minor.” In weighing that determination, the district court turned to the factors cited by the
    Sentencing Commission in its comment in the Application Note supporting U.S.S.G. § 2D1.1.
    These four factors included: (1) the quantity of hazardous chemicals and the manner in which
    they were stored, (2) the manner in which the chemicals were disposed, (3) the duration and the
    extent of the manufacturing operation, and (4) the location of the factory and number of lives
    placed at risk. U.S.S.G. § 2D1.1, cmnt. n. 18(B)(i). As chemical disposal, the second factor,
    was not at issue, the district court focused on the three remaining factors.
    Regarding the first, the district court determined that, while the quantity of chemicals was
    low, it was nonetheless highly dangerous. In addition to the flammable chemicals found outside
    the bottle, the district court noted that the lithium inside the bottle could react with moisture to
    cause an explosion. As to the third and the fourth factors, the district court determined that
    materials previously used for manufacturing methamphetamine were then stored in a moving
    vehicle. And while the ride may have been short, loosely storing those chemicals together in a
    bag and then transporting them by vehicle was an inherently dangerous endeavor, one that raised
    the possibility of “extreme injury” to a minor. For these reasons, the district court overruled
    Owen’s objections and applied the sentencing enhancement.
    Owen moved for a downward variance, asking the district court to impose a 180-month
    sentence. That sentence was sufficient, Owen contended, in view of his background and mental
    health history. Agreeing that Owen had shown he suffered from a mental illness, the district
    court nonetheless noted that Owen had not demonstrated a specific diagnosis or condition. Nor,
    more critically, had Owen demonstrated how that mental health condition contributed to his
    criminal behavior. Accordingly, said the district court, Owen failed to demonstrate that a
    downward variance was appropriate. After examining the purposes of sentencing set forth in
    18 U.S.C. § 3553(a), the district court sentenced Owen to a 250-month term—the bottom end of
    the applicable Sentencing Guidelines range.
    No. 18-5736                         United States v. Owen                                 Page 7
    II. ANALYSIS
    A.     Owen Created A “Substantial Risk Of Harm To The Life Of A Minor.”
    One issue is front and center in this appeal: Whether Owen created a “substantial risk of
    harm to the life of a minor” through his conduct involving manufacturing methamphetamine.
    U.S.S.G. § 2D1.1(b)(14)(D). The district court concluded that he did and increased his sentence
    accordingly.
    Owen challenges two aspects of the holding below. One, that the district court erred in
    finding, as a factual matter, that Owen transported in a vehicle dangerous items that presented a
    risk of harm to a minor riding in the vehicle. And two, even if those findings were correct,
    Owen’s conduct, as a legal matter, did not present a “substantial risk of harm” to the minor. To
    Owen’s mind, any “risk” was at most speculative, and not grounded in science.
    “[W]e review for clear error” the district court’s “factual findings.” United States v.
    Corrado, 
    304 F.3d 593
    , 607 (6th Cir. 2002) (citations omitted). “If the district court’s factual
    findings are not clearly erroneous,” then we review “de novo the determination that the conduct
    in question constituted relevant conduct” under the Guidelines provision at issue. 
    Id. (citations and
    internal quotation marks omitted).
    1.      The district court’s factual findings were not “clearly erroneous.”
    Much of this case turns on the district court’s factual findings regarding the items and
    materials Owen was transporting. In light of our “clear error” standard of review, Owen has a
    tall hill to climb in challenging those findings. To our eye, he has not done so.
    In issuing its factual findings, the district court thoughtfully considered the record below.
    The district court found that Owen manufactured methamphetamine and after having done so,
    put the manufacturing instruments in a bag. Those instruments included a one-pot, in which
    chemical reactions had previously occurred. In the one-pot, the district court concluded, there
    remained sludge containing lithium particles or pieces, along with water or moisture.
    The district court likewise found the existence of other “dangerous and extremely hazardous”
    materials in the bag, a collection of items that, together, presented a risk of explosion. And yet
    No. 18-5736                          United States v. Owen                                Page 8
    Owen then placed that bag in a vehicle—the one both he and a minor were travelling in when
    stopped by an officer.
    Testimony at the sentencing hearing confirmed these conclusions. Wilkey testified that
    he found a bag containing a “one-pot shake bottle.” Shelton testified that the one-pot contained
    “meth sludge.” And, he explained, the sludge that remained in the bottle would have contained
    unreacted lithium and water or lighter fluid. Shelton also testified that the other chemicals found
    in the bag could “cause chemical burns” so severe that they would “eat[] your skin.”
    All told, the district court’s factual findings were not clearly erroneous. See 
    Corrado, 304 F.3d at 607
    .
    2.      The district court properly applied Guidelines § 2D1.1(b)(14)(D).
    Accepting these factual findings, we turn to the district court’s determination that this
    chain of conduct presented a “substantial risk of harm to the life of a minor.”          U.S.S.G.
    § 2D1.1(b)(14)(D). Unlike our more cramped review of the factual findings below, we take a
    fresh look at the district court’s interpretation and application of the Guidelines provision.
    But even with a fresh perspective, we find no error in the district court’s application of
    § 2D1.1(b)(14)(D).
    1. In what circumstances does one, in illegally manufacturing methamphetamine, create
    a “substantial risk” of harm to another? Although the Sentencing Commission has not expressly
    defined that phrase in § 2D1.1, the Commission has offered a commentary in the section’s
    Application Note to help us interpret the provision. There, the Commission identified four
    factors that, to its mind, inform the “substantial risk” determination:
    (I) The quantity of any chemicals or hazardous or toxic substances found
    at the laboratory, and the manner in which the chemicals or substances
    were stored.
    (II) The manner in which hazardous or toxic substances were disposed,
    and the likelihood of release into the environment of hazardous or toxic
    substances.
    (III) The duration of the offense, and the extent of the manufacturing
    operation.
    No. 18-5736                           United States v. Owen                                Page 9
    (IV) The location of the laboratory (e.g., whether the laboratory is located
    in a residential neighborhood or a remote area), and the number of human
    lives placed at substantial risk of harm.
    U.S.S.G. § 2D1.1, cmnt. n. 18(B)(i).
    The Application Notes and supporting commentary reflect the Commission’s
    interpretation of the Guidelines.      Stinson v. United States, 
    508 U.S. 36
    , 41 (1993).       That
    interpretation, of course, is not binding in the way an agency rule would be, where the rule has
    journeyed through a formal rule-making process, including the notice and comment aspects. See
    United States v. Havis, 
    927 F.3d 382
    , 385–86 (6th Cir. 2019) (en banc). Where an agency rule is
    considered ambiguous, we typically afford some deference to the agency’s interpretation of the
    rule. See Auer v. Robbins, 
    519 U.S. 452
    , 461–62 (1997). But when to do so, and what standards
    to apply when we do, are at the moment matters of some debate. See Kisor v. Wilkie, 
    139 S. Ct. 2400
    , 2416 (2019) (noting that “not every reasonable agency reading of a genuinely ambiguous
    rule should receive Auer deference”); 
    Havis, 927 F.3d at 386
    (“[W]e need not accept an
    interpretation that is plainly erroneous or inconsistent with the corresponding guideline.”)
    (internal quotations omitted). For now, we need not wade into those murky waters. As no party
    has challenged § 2D1.1(b)(14)(D) as ambiguous, as the Application Note in question does not
    purport to add to or change the ordinary understanding of the section, as we largely embrace the
    interpretation included in the Application Note, and as no party has challenged any aspect of the
    Application Note, we see no issue in referencing the principles therein as an analytical starting
    point.
    But those factors are just that—a starting point. We can narrow these factors even more
    where there is no issue with respect to the disposal of toxic substances (factor II). See U.S.S.G.
    § 2D1.1, cmnt. n. 18(B)(i)(II). And as to the Application Note’s three remaining factors, they in
    some ways cover common ground.              We can thus sharpen these factors into two key
    considerations to guide our assessment of “substantial risk” in this setting: (1) the likelihood the
    conduct at issue risks harm to another (in this case, a minor), and (2) how serious that harm
    might be, should the risk come to pass.
    No. 18-5736                        United States v. Owen                              Page 10
    In weighing these factors, some cases will be easy. Where the conduct at issue is likely
    to cause harm, and the harm that ensues would be severe, that course of action would easily
    satisfy the “substantial risk” test. By the same token, where the likelihood of harm is low, and
    the harm most likely to ensue is not serious, that conduct seemingly would not reach the
    “substantial risk” threshold.
    Those are the easy cases. More difficult is a case, where, like here, the likelihood of
    harm is tangible but low, but the resulting harm catastrophic. Or where the likelihood of harm is
    high, but the likelihood of severe harm is tangible but low. In each setting, we must weigh those
    dual considerations to determine whether they together satisfy the “substantial risk” standard.
    By and large, that analysis is more qualitative than mathematical. See Jones v. United States,
    
    527 U.S. 373
    , 408 n.8 (1999) (Ginsburg, J. dissenting).
    2. Application of these two guideposts cut across our cases applying § 2D1.1’s
    “substantial risk of harm” standard. Start with United States v. Layne, 
    324 F.3d 464
    (6th Cir.
    2003). There we applied the sentencing enhancement for endangering human life, U.S.S.G.
    § 2D1.1(b)(14)(C) (then numbered as U.S.S.G. § 2D1.1(b)(6)(A)), a parallel provision to the
    enhancement for endangering the life of a minor. 
    Layne, 324 F.3d at 468
    –71. In assessing
    whether the conduct at issue risked harm to another, we noted that several dangerous chemicals
    were present at the manufacturing lab for more than two weeks. 
    Id. Thus, there
    was a relatively
    high likelihood of an explosion. And because the laboratory was housed in an apartment, a
    “densely settled area,” if an explosion did occur, it was likely that one or more people would be
    severely injured. 
    Id. at 471.
    In United States v. Davidson, 
    409 F.3d 304
    (6th Cir. 2005), these factors weighed the
    other way. In Davidson, there was a low probability that the laboratory in question would
    explode or catch fire. The defendant did not have a large quantity of chemicals, and the
    manufacturing operation had not been in place for any extended period. 
    Id. at 313.
    Equally low
    was the chance of harm, should an explosion occur. The defendant kept the methamphetamine
    laboratory in a locked barn loft in a remote location, and precautions had been taken to keep
    people away from the operation. 
    Id. at 314.
    Because the risk of harm was low, and the
    likelihood of grave harm equally low, we denied application of the enhancement.
    No. 18-5736                         United States v. Owen                              Page 11
    3. Today’s case falls somewhere between Layne and Davidson. In evaluating the risk to
    another caused by Owen’s conduct, we consider the location of his manufacturing-related
    conduct.    Owen placed his manufacturing materials in a vehicle, making that vehicle the
    methamphetamine laboratory for purposes of our sentencing analysis. See United States v.
    Pinkerton, 279 F. App’x 382, 384 (6th Cir. 2008) (holding that it was not erroneous for the
    district court to treat the defendant’s vehicle as a laboratory). To be sure, the typical case
    involves a more constant laboratory space, like a home, shed, or barn. But we see no reason to
    treat a vehicle differently. After all, if one who implements some, but insufficient, safety
    measures in a static laboratory can create a substantial risk to others, so too can a person who
    implements no safety measures while transporting those same laboratory materials. See 
    id. With respect
    to the risks presented by Owen’s methamphetamine laboratory, the district
    court determined that transportation of lithium in a vehicle was “not a safe activity.” That
    lithium—along with several other dangerous chemicals—was transported “without any safety
    precautions.” The one-pot and chemicals were found in a bag, emphasizing Owen’s lack of
    safety measures. And while the cook operation occurred prior to the vehicle ride, not during it,
    transportation of manufacturing equipment and materials by vehicle presented its own safety
    risks.
    The district court likewise noted the serious harm to a minor that would likely have
    occurred had those these risks come to pass. The combustible bag was confined in a vehicle, in
    close proximity to the minor. Suffice it to say, in a moving vehicle, there is no escape route in
    the event of an explosion. It thus takes little imagination to see that any combustion would have
    been significantly likely to cause grave harm to that minor.
    For these reasons, we agree with the district court’s application of the sentencing
    enhancement. While the quantity of hazardous substances was low and combustion far from
    inevitable, the dangers posed were exacerbated by the way the substances were stored. And no
    one can question the grave risk an explosion would have presented to the seven-year old riding
    alongside those materials. See, e.g., United States v. Finch, 342 F. App’x 565, 569 (11th Cir.
    2009) (applying enhancement where defendant had “transported anhydrous ammonia in an
    unapproved container and in a vehicle occupied by [his] two-year-old daughter”).
    No. 18-5736                         United States v. Owen                                Page 12
    All of that said, this case is undoubtedly close. As to the risk of harm, there was not an
    overwhelming likelihood of an explosion in the vehicle.          By the same token, we cannot
    understate the harm an explosion would have caused. Upon careful consideration of the unique
    facts of this case, we hold that Owen created a “substantial risk of harm to the life of a minor.”
    Even a small chance of combustion can create a “substantial risk” when the combustible material
    is transported in a dangerous manner, in a confined space, in the presence of a minor.
    4. Owen makes several counter points. First, he contends that any risk to a minor
    presented by his conduct was not substantial, citing as support our decision in Davidson. There,
    as noted, we reversed a district court’s application of a “substantial risk” enhancement where the
    methamphetamine laboratory at issue was locked in a barn in a remote location. 
    Davidson, 409 F.3d at 313
    –14. That is a far cry from this case. Owen did not take efforts to safely store his
    laboratory materials, as was the case in Davidson, nor can a bag in a vehicle be considered a
    remote location when a child is on board.
    Owen next takes issue with the government’s reliance on Finch. He distinguishes that
    case on the grounds that he did not transport anhydrous ammonia, and that as to the substances
    he did transport, the government failed to prove they were dangerous. Yes, the chemicals may
    not be the same. But a risk of combustion is a risk of combustion, no matter the material in
    question. And here, the evidence revealed that both water and lithium had to be present in the
    materials previously used as a one-pot for manufacturing methamphetamine. Owen does not
    contest that this collection of items, taken together, were combustible, nor does he contest that he
    transported them in a vehicle with a child.
    Next, Owen offers several alternative definitions of “substantial risk,” definitions that he
    believes are better suited for analyzing his conduct. Owen finds those definitions in cases
    addressing the Armed Career Criminal Act (18 U.S.C. § 924(e)), the Eighth Amendment to the
    United States Constitution, and the Ohio Revised Code. Assessing risk in those unique settings,
    however, involves different considerations and different underlying objectives. While non-
    binding, the Sentencing Commission provided a list of factors to consider in determining
    whether a “substantial risk of harm” was posed. In a case like this one, where environmental
    No. 18-5736                          United States v. Owen                               Page 13
    concerns are not present, we can distill those factors down even further, to the two noted above.
    We rely on those considerations here.
    But, says Owen, if we affirm his enhancement here, our test amounts to no test at all.
    To the contrary, we have given examples of when that test will—and will not—be met. And we
    have described this case as very close. Yet in applying the two factors articulated above, we
    believe they tip in favor of applying the enhancement. To repeat: Owen did not merely transport
    methamphetamine-making         material    in   a   vehicle;   he   transported   previously   used
    methamphetamine-making materials, including a container of lighter fluid, along with a
    combustible mix of lithium and liquid, in a vehicle, in a dangerous manner, with a minor present.
    Such a grave threat to the life of a minor, even if not overwhelmingly likely to come to pass,
    safely falls within the “substantial risk” heartland.
    It bears repeating that there will be cases when § 2D1.1(b)(14)(D) is more easily
    satisfied—that is, cases where the likelihood of harm to a minor is even greater. See, e.g., United
    States v. Merrell, 213 F. App’x 402, 405–08 (6th Cir. 2007) (applying enhancement to defendant
    that possessed vast amounts of toxic chemicals, disposed of hazardous waste in trash cans, had
    been manufacturing for more than two years, and did so in a home where multiple minors lived.)
    While today’s case may be closer to the margin, a preponderance of the evidence supports
    application of the § 2D1.1(b)(14)(D) enhancement. See United States v. Angel, 
    576 F.3d 318
    ,
    321 (6th Cir. 2009).
    B.     Owen’s Sentence Was Not Substantively Unreasonable.
    Owen also argues that the district court abused its discretion by denying his motion for a
    downward variance and entering a substantively unreasonable sentence. Owen bases these
    challenges primarily on the fact that he suffered from a mental illness.
    The district court sentenced Owen to 250 months—the very bottom end of the sentencing
    range proposed by the Guidelines.          In assessing whether that sentence is substantively
    unreasonable, we in essence ask whether the “sentence is too long.” United States v. Rayyan,
    
    885 F.3d 436
    , 442 (6th Cir. 2018). In so doing, we assess whether the district court balanced the
    18 U.S.C. § 3553(a) factors correctly or if it placed too much weight on some factors, not enough
    No. 18-5736                         United States v. Owen                                Page 14
    on others. 
    Id. Our standard
    of review is deferential. United States v. Parrish, 
    915 F.3d 1043
    ,
    1047 (6th Cir. 2019), petition for cert. filed, (U.S. July 2, 2019) (No. 19-5123). We give
    considerable deference to a district court’s decision about the appropriate length, and we treat a
    within-Guidelines sentence, like the one Owen received, as presumptively reasonable. Id.; see
    also United States v. Sexton, 
    512 F.3d 326
    , 332 (6th Cir. 2008). And rebutting that presumption
    is “no small burden;” we “will not generally second guess sentences on substantive grounds
    when they fall in the range prescribed by the Guidelines.” United States v. Simmons, 
    587 F.3d 348
    , 365 (6th Cir. 2009) (citation omitted).
    While a district court should, in the sentencing context, give consideration to a
    defendant’s mental illness, the court is not required to grant a defendant’s motion for a
    downward variance whenever a defendant suffers from such an illness. See, e.g., United States
    v. Tolbert, 459 F. App’x 541, 547–48 (6th Cir. 2012) (affirming district court where it
    acknowledged that defendant suffered from a mental illness but found that the need to protect the
    public required a Guidelines-range sentence); United States v. Mills, 364 F. App’x 217, 220–21
    (6th Cir. 2010) (affirming district court’s within Guidelines-range sentence where the
    defendant’s mental illness did not explain his criminal activity). Although the district court here
    ultimately denied Owen’s motion for a downward variance, the court did consider Owen’s claim
    that he suffered from mental illness. The district court first considered the PSR, which offered
    the opinion that Owen’s mental illness did not impair his ability to appreciate the wrongfulness
    of his actions. Although Owen objected to some portions of the PSR, the district court adopted it
    without change.
    The district court then considered Owen’s mental health history in addressing the
    18 U.S.C. § 3553(a) factors. The district court “credit[ed] the defendant’s argument that he does
    suffer from a mental illness” but noted that Owen had failed to present evidence that allowed the
    court “to specify exactly the type of the illness or the correct diagnosis,” or whether that illness
    contributed to his criminality. The district court added that Owen’s sentence must be “sufficient
    but not greater than necessary.” The district court weighed those considerations against Owen’s
    “very, very serious” criminal conduct. The district court also highlighted the need to deter others
    from engaging in the same conduct, and the need to protect the public. Against this backdrop,
    No. 18-5736                      United States v. Owen                          Page 15
    we cannot say that the district court abused its discretion by denying Owen’s motion for a
    downward variance and imposing a 250-month sentence.
    III. CONCLUSION
    For these reasons, we AFFIRM the judgment of the district court.
