I recently read about a truly amazing guy. And because I am kind, I will spare you the trouble of reading about a truly amazing guy.
Does anybody remember the movie Super Size Me?
It was a documentary about a guy who ate nothing but McDonalds for 30 days. He gained a bunch of weight, his cholesterol shot up, and he got pretty sick in general. This got lots of publicity and McDonald's got in lots of trouble.
So, enter Joe. Joe is a marathon runner, and from the little I know about marathons, he is quite good (personal best time: 2:36). (My personal best time: 7 years). Joe loves McDonald's, so he decides to do the same thing. For the 30 days before the LA marathon, he ate nothing that he didn't buy at McDonald's (the only exception being water and that weird sugar-goo that runners eat while they're running). He continued training, and running, and all that during the month. In the end, his vitals were as good as they were before, and he beat his personal best time by a few seconds, still finishing in 2:36.
I love this story. I could go on about the moral of the story, but I think it's obvious.
Now if only somebody would run a marathon after eating Pizza from the Diag Party Supply store across from my lab, I would feel much better (I'm pretty sure that Diag Pizza is technically considered a chemical weapon, but a very tasty chemical weapon).
