Keep in mind, we can prevent or reverse cancer, diabetes, neurodegeneration, and infertility (depending upon how far down the path to destruction you may have wandered). You might have noticed many of these diseases occur together. Heart disease and depression. Infertility and autoimmunity. This is because these seemingly sepearate diseases share an underlying mechanism: Inflammation. Inflammation is a natural process that we will die without, but we will also die with too much. This is a case of Goldilocs wanting things to be "just right."
I'll find some more interesting stuff to post about tomorrow. I need to get to bed. I think I've cried enough for tonight :\
