According to the National Eating Disorders Association, approximately 90%-95% of anorexia nervosa sufferers are girls and women. And it's often assumed the majority of sufferers are white. But the disorder isn't limited to any demographic. A new book, Going Hungry (releasing on September 9) highlights the stories of 19 different anorexia nervosa survivors -- including stories from women, men, and minorities.

One of the shared stories is from Rudy Ruiz, who -- after being taunted and teased as a chubby child -- began trying to lose weight unhealthily during his high school years. He drank gallons of diet iced tea and ran five miles a day, ultimately dropping to 104 pounds -- far too thin for his 5' 7" frame. His initial desire to shed some extra pounds had turned into an obsession. He'd later learn that he had anorexia nervosa. Today, Ruiz is 40 and a two-time graduate of Harvard. He admits that while is healthy now, he still struggles with the obsession.

If you or someone you know might be suffering from anorexia nervosa or another disorder, visit the National Eating Disorders Association for information and support.

Although many studies have been done on the negative effects that sleep deprivation has on the performance of athletes, not much has been done on how extra sleep affects athletic performance. But recently a small study was done by taking 6 basketball players from the Stanford University team and measuring how stats like sprint times and free-throw percentages were affected by extra sleep. For the first two weeks the players kept with their normal sleeping habits, and for the second two weeks they were asked to get as much sleep as possible. When their individual athletic statistics were compared they all did better in the second two week period compared to the first.

My only question is this: How do the researchers know the athletes were getting enough sleep in the first place? I don't know many college kids that regularly get enough sleep every night, so maybe this was just another test of sleep deprivation (the first two weeks) versus getting enough sleep (the second two weeks) -- not necessarily getting extra sleep.
