Soldiers have a tough job, and necessarily most of them have a lot of physical strength and endurance. They are also capable of staying awake for long numbers of hours and living oftentimes in less than ideal condition. Former U.S Army General Stanley Allen McChrystal certainly fits the frame of a strong, enduring man.
It is reported that he regularly runs 7-8 miles. He sleeps very little: about four hours and, even with all the hours he is awake, only eats a single meal. While some people are pretty ambitious runners and lots of college students survive on just a few hours of sleep, the combination of heavy exercise, little sleep, and a single meal are incredible!
McChrystal was very successful in his military career. However, a public comment about his recommendation to send 30,000 to 40,000 more troops to Afghanistan caused him to lose his position as a commander. He lost his position because in making such a comment he let out information that should have been kept a secret.
Nevertheless, he kept his four stars when he resigned from the army and remains a soldier with many medals and awards.
