I know a man in his late seventies. Can work outside in the heat for hours without flinching, has no major health issues and he never touched alcohol once in his whole live. I have a hard time thinking that his abstinence is unrelated to his longevity. On the other hand, some people's bodies seem to be able to handle it. 

I'm sorry to hear about your friend. I'm the type who thinks that a principled life needs to have some exceptions - this is a good example.

Do you drink?

I used to drink quite a lot, but I gave it up when I finally decided to lose weight and get in shape. After taking a break from drinking, I found out that when I drink, I lose my motivation for days after. I went over 2 years without a drop, until recently, I had one beer in honor of my friend who passed away. I doubt I'll drink again anytime soon.
