Trippin, my husband is the same except he is a heavy smoker. He says he will smoke until the day he dies, that it is one of his few pleasures in life. He tells the kids, "I smoke so you don't have to." Ha!
I've always had a feeling that if I keep going and don't quit eventually, that I would end up with lung cancer and that scares the crap out of me. Those smoking ads scare me too. Besides that, I just want to set a good example for my kids.
