FWIW, for me personally it's not a strong or bad smell, and it's pretty neutral. So, I don't think anyone needs feel self-conscious about it!
Sensation fades rapidly. I have little doubt younger friends and colleagues get more of it, alas.
And I’ve never been a smoker — I tried smoking a pipe in college, but could never keep the damn thing lit. And cigarettes just made me gag and tasted horrible. Of course, I knew plenty of smokers and my mom was a heavy smoker for many years, so I knew what the smell was like. That didn’t bother me so much, but the act of trying to smoke did.
So far as I can tell, I just now smell like my grandpa used to when I was a kid.
Anyway, I’m not sure what to make of this situation. It still bugs me, from time to time.
I wonder if HN's users have some insights to share?
