I am very glad that I never started smoking. But most of that was because I was never in any circumstances that would be conducive to me starting. Excepting, of course, the fact that both of my parents were smokers from age 15. My sister started just before she turned 18. I'm 21 myself.

I know it must be extremely tough to quit though. I can only imagine what it would be like to give up a substance that your body was convinced it needed. Kudos to all who have given up, or are trying to. I can only aspire to have those kinds of guts.
