As an aside, I recently had this horrible moment of realization. Much of the fitness advise given out is just so incredibly wrong, and I am able to realize that because I have a strong background in that subject. But I realized, 90% of the stuff I read about are areas I don't have a great background in. I could be accepting really wrong facts in other areas that are just as wrong as the nutritional facts I scoff at, and I would never learn of my error.
