People that disagree with quitting smoking.

I know quite a few people that disagree with quitting smoking, i'm about to list their points.Sorry, I feel the need to post this.- "I really enjoy smoking,stop smoking, why should I give that up?"My reply to this was "Lifes short and once you experience smoking once,stop smoking now, it's really nothing new.. so if you want to slice years from your life for a generic experience that does nothing for you go ahead."Long story short the guy really couldn't see my point and proceeded to quote "To live life is to skid sideways in your coffin with a glass of wine in your hand and a smoke in your mouth screaming AGAIN!" even if i'm quitting I kind of agree with him.- His friend then used my original arguement against me which I have heard many passionate smokers say "Your right life is short and I only want to be alive for the ups." the point to his arguement ended up being that the final 50 years of your life arn't worth it.- I've also heard people say "Smokings not as bad as people make out." they proceed to tell me how there 97 year old grandad was a 3 pack-a day reds smoker and that basically "Smokings worth the risk, you could die in a car accident on the way home."I mean their arguements arn't that far fetched, I know what there talking about..What do you think?
