re: Parents that smoke in playgrounds

It is up for debate whether certain things cause cancer or not. Smoking is not one of those things. Regardless of the debate about how it does or doesn't infringe upon people's rights in public....why would anyone smoke knowing that it causes cancer. What is so appealing about the experience knowing what we all know about it now?

When I grew up I drank coke for every meal. I rarely drank water. My whole family did this for the most part. Now that I am an adult and can make my own decisions and realize how bad soft drinks are for you (health and teeth), I gave them up and never went back. If things are bad for you, why do them period?
