I can jump in here as well. I smoked, still smoke. Daughter grew into a beautiful gal who has a babe of her own now. My daughter is strong as an ox, working out at the gym 3-4 times a week since she was a teen-ager. Smoking hasn't slowed her down one bit.
She and her hubby both smoke, with all the anti's out there, they do not smoke around their son. That's what Social Services has done today. Threaten smokers with losing their kids if they are caught smoking around the offspring.
I remember when doctors used to smoke while with their patients.
