azernik already answered regarding the drive. Just wanted to comment regarding:<p>&gt; At least, when you eat too much, you&#x27;re only harming yourself.<p>That&#x27;s not true, just as &quot;if you smoke &#x2F; drink you&#x27;re only harming yourself&quot;. Provided you have a family you&#x27;re putting them at risk of your early death. You&#x27;re both passing down more likely obesity when pregnant (2015 study, but don&#x27;t have time to google it now) and teaching kids the behaviour that likely leads to obesity for them too.<p>So yeah, you&#x27;re actually harming your family not just yourself.
