I have been a heavy smoker since I was 18, Quitting is unlikely. I also have a bad back, fall allergies, and get occasional migraines and frequent coughing spasms. These things take their toll on you.
I do eat healthy and exercise, but I'm not expecting to get past 70. It's a sobering thought my life is probably like 2/3 of the way through already, but it doesn't bother me all that much. I have no desire to be old (ie. confined to a wheel chair, unable to remember my name, etc.). Actually, I never thought I would reach 40 when I was a teenager. I guess I didn't drink as much I thought I would
What about the rest of you, how long do you think you will live?
