I don't smoke, though I know in my parent's generation rare was the person who didn't. But, second-hand smoke is pretty bad, too.
Being a nurse, I've seen a lot of illness caused directly smoking and indirectly by smoking. If I can prevent an illness which has the potential to wreck physical and financial havoc, I'll do all I can.
Please, ANYONE who is considering starting to smoke, DON'T and anyone who is considering quitting, I applaud your efforts and wish you all the success in the world. You owe it to YOU!
