For all those that haven't quit, I'll give you another reason.

I have been suffering from a pretty bad cold (coughing so bad that I was on the floor, pulling muscles in my back, abdomen and accross my shoulders) which has gone on for three weeks.

The doctors didn't know what was going on and were treating me as best they could with little result.

When I told them that I didn't smoke but had grown up around smokers they changed the treatment regimen totally and radically.

I'm recovering nicely now, but now that I know that it does make a difference I will never allow my children to smoke or be near smokers. If not for your health, please quit for your loved ones and those around you.
