What Will Be My Life Span If I Continue Smoking 1 Pack Cigarette A Day?

I am smoking since the previous 20 years with an average of daily a pack. Now I am 40 years aged. What would be my life span expectancy with continuing the smoking as usual and I am also desiring to know what would be my life span, if I quit the smoking right now.

See, this is where the medical literature is totally messed up........ Any answer I can give is really messed up and inaccurate except for
"Lower, that's definitely true."
First, smoking that levels doubles the rate of lung loss. That's pretty much everyone, guaranteed. But that lowers maximal life expenctancy from over 100 yr to about 80.
BUT, if you're one of the 10-20% who get an allergic like reaction to cigarettes and start coughing up your lung (COPD) then the rate of lung deterioration more than doubles again ! and you're on oxygen before age 70.
If you have risk of heart disease, then smoking doubles to triples it
If you get lung cancer (about 10% lifetime risk w. cigs... below measureable risk without cigs) then really bad.
It's like mixing men and women into risk of breast cancer to get an average.
Best case, 110 down to 80; worst case, lung cancer next year.
