Best way (for you) to do that is to quit.
Another way would be to develop lung cancer, but that's not so nice for you though it might shock the kids into never wanting to touch a fag ever.
Actually, it's emphysema that runs in my family. I believe it took out grandma, a couple of aunts and uncles, and my Dad has had it for quite a while too. (Actually Dad has outlived at least one of his doctors.) A couple of years ago they misdiagnosed me with the onset of COPD.
