awesome article/infographic by Cliff Kung explaining what happens to athletes if they don't get 10-12 hours of sleep per week:
and another infographic calling out specific athletes and telling how much they sleep.
check out lebron and federer!
kung finishes the article posing the question - do athlets sleep so much b/c they need to be at their peak at all times. OR do they sleep so much b/c they have more free time than the general population?
I'd go with the former - you'd be surprised at how much athletes need to dedicate to their sport even when they aren't physically working out.
