They say you first need to be able to care for yourself before you can care for someone else.

That's especially true for the role of president , it turns out. Sometimes napping is way more beneficial than blearily taking on one more stack of documents and making important decisions while fatigued. Great leaders know this.

While it probably seems like there aren't enough hours in a president's day to focus on personal wellness, the practice is exactly what will make a person equipped to perform the role to their best. President Obama's most recently released health records, for example, reveal that he's in great shape and has even lowered his cholesterol during his presidency . His healthy diet and exercise regimen certainly help him serve the country every day.

If we want our president to be smart, responsible and effective, we need them to be well-rested , properly fed and endorphined-up from a good workout . All three of these measures of health can help keep the time-pressed and super-stressed from cracking under pressure.

We've reviewed the six remaining presidential candidates' health habits for clues as to how they might keep up their wellness routines while living in the White House (the gig does, after all, come with a personal chef and trainer ). See their habits below. Do you think any of them require makeovers? Let us know in the comments section.
