Why? Because they kill you? Well auto accidents kill you too, as well as water, skiing, sleeping, drinking, sex, crapping etc. My point is anything could kill you, and theres a good chance you could die young anyways. Life is short, do whatever the hell you want, just dont give other people shit for their own choices, you dont see me giving you shit for listening to lil'wyte, one of the worst "rappers" I have ever heard.
