The Petraeus bodyshop, in perspective
If one thing unites the great commanders from Attila to Washington, it has been their raw ability to sleep less, eat less, and drive harder than anyone else on the battlefield. The Duke of Wellington caught some nice breaks at Waterloo, but he also made his luck by spending 10 hours a day in the saddle on a single cup of tea, sleeping two hours a night, and limbering up each morning by walking briskly for 30 minutes while swinging a riding crop.
Judging by thousands of years of military history, the general isn’t doing too much. The rest of us have gotten used to too little.
