Fast food restaurants get lots of criticism for serving up fatty, salty, calorie-dense fare. But Don Gorske has no complaints. The 57-year-old retired prison guard was just honored at his hometown McDonalds for eating his 25,000th Big Mac - a feat that took him 39 years to accomplish.
Gorske, who was featured in the 2004 documentary "Super Size Me," is slim, takes regular walks, and was recently given a clean bill of health by his doctor.
Gorske admits his motivation may be more rooted in his mind than his belly. He says he loves numbers and repetition, and suspects he may have obsessive-compulsive disorder. If that's true, he's not alone. More than 2.2 million Americans have obsessive-compulsive disorder, and experts say food is often a focus.
