So, not to be a Donnie downer (but I suppose I am) I enjoyed smoking in my youth till I didn't. I was a heavy smoker from about 17 until I quit cold turkey at 43. I was one of those idiots who thought I'd smoke and stop just before I got sick.
I did end up paying the piper. Bad cardiac genetics on my father's side. So triple bypass surgery at 54, a heart attack at 68 and three trips for stents. Also been diagnosed with moderate emphysema. That said, there are those who smoke all their lives and live to 100. Some win the genetic lottery and some don't.
I do refuse to give up the alcohol though, A nice gin and tonic or a hit of bourbon helps keep life fun. Bombay Saphire or a good high proof like Wild Turkey 101 or Old Grand Dad Bonded suit me fine.
