I started the night before I turned 13 so it was 46+ yrs overall. I was a pack+ per day for many years. But I stopped imm with vaping since all we really want is the nicotine- that's how I reasoned it anyway. I have only wanted to smoke a cpl of times ... but I don't smoke anymore, lol, so I just vaped thru it. I quit on 9.17.11 and turned 60 this year. My sense of smell came back so strongly that sometimes it's TMI, ha.
I think the age of 13 was the most popular time to start smoking. Some one on this forum tried to do a survey for that and I remember the age 13 being used a lot... I started at 13 - sneaking my uncles smokes...
I know what you mean about smells - I did not know there were so many in the world that are so offensive until I got off the smokes...
