True, so does the air we breathe, the water we drink, and the food we eat. Your statement is factual; so what is your point?

"Everybody gotta die sometime, Red."(Tom Berenger as Seargent Barnes in the movie Platoon)

People die everyday from voluntary activities. Heck, my doctor refers to grapes as "little sacks of poison". What are you gonna do, stop breathing, or walk around with an air purifier on your back 24/7?

It is quite easy, sitting here in Baghdad, to make the statement that "you do what you gotta do" to get by in this life. A vast majority of the people on this planet do not have the luxury of worrying about the long term health risks of something that otherwise makes them feel a little better. You are going to have a hard time convincing me to give up my weekly beer ration when mortars are falling around me.

However, if you feel the conviction to deprive yourself of one of life's basic pleasures, by all means. That will just leave more for the rest of us, and in 80 years or so none of us will be here to know the difference, right? Who wants to live forever?
