I'm beginning to wonder about you Matt.
Whenever there is a thread about coke you are all over it espousing the glories of cocaine, then you say
"but I'd never touch the stuff" or something to that effect
In short, because I am a pussy. I like to call myself a "rational hypochondriac" in that I know I am one and that it is irrational. I also don't know what my genetics are like and I know that leading a clean life will optimize my lifespan. If I'm going to get cancer at 35, it's going to happen. But if I live a clean life I might get three more years out of the deal. There's more to it than that, but that is the size of it roughly.
