I always smoke people 
But anyway, I believe you are referring to some people who gives u
the impression they are gonna live longer just because they dun
smoke right....?
But I am sure there are some who are genuine in their
concern...
like I met one kid who is just 15 and smoking at a funeral wake of
a friend.... So i just went up and talk to him and find out why he
is smoking, so he says, friend smoke so i smoke. I ask him whats so
good abt smoking... he says, nothing good but he dun see anything
bad also, just like money disappear faster.... I kinda agree with
him because it is hard to see what is so bad abt smoking actually
so I never pushed people in that direction but for him, money is
really an issue cos he spent his pocket money all on ciggies.... so
right now I am following up with him to slowly quit smoking or like
what I tell him, slowly cut down on his 2 packets a day.... (i
think thats quite alot for anyone, not mentioning he is just
15).... well it has been a few mths and progress is slow, right now
I think he is at slightly more than 1 and half pkts per day.... I
believe he will quit smoking one day or at least cut down to a
manageable amount...
What I am trying to say here to non smokers is that, sometimes,
action speak louder than words. If you are really concerned about
the smokers, then do something to help them or at least offer to
help them in any ways you think you could.
Smokers, there are people who are sincere lah when they make their
comments, be more open abt it.... anyway, its really a strain on
the wallets lah, so why not at least try to cut down to a
manageable volume.... if you tell me you are social smoker, then I
am fine with that lah, its up to the person or like one friend tell
me, "I am rich what...." 
then i shut up liao hehehe
