there is that (as someone who had parents and grandparents who were smokers) but it is also quite unfair, you never asked for them to be smokers or smoke around you and when you are a child your attempts to convince them to stop smoking is met with laughter more often than not.

I think a big part on why I'm not a smoker is I saw what it did to people, and how second hand smoke has affected me. I'd be in a room with my mother and grandfather, trying to find clean air inside my grandfather's small apartment because both of them were smoking at the same time. I never want to make another human experience that.

Best thing you can do is to break the chain if others in your family do it I guess. I will never smoke, there's literally nothing in it for me or those around me.
