Stanley A. McChrystal

Age: 58

Rank: General

Allegiance: United States of America

To be the Army General of a nation and to control all U.S. and NATO forces in Afghanistan a normal officer would need immense amount of energy to perform his job. This would be possible only with proper meal and sleep every day.

McChrystal does not need all such things to get him going, according to Time; he eats only one meal a day and sleeps for just four hours a night.
