My hubby is a heavy smoker,2 packs a day!I cant even talk to him about quitting,he gets mad.Our son had allergies when he was a baby,the pediatrician wanted him to stop smoking in the house.He would not do it.The rooms have nicotine on the walls,it permeates everything I gave up trying to keep a fresh smelling house years ago.Considering a good burial policy on him,we feel he will need it soon. His mother died from smoking.The habit is very expensive & I am sick of the odors.40 years is enough!The 2 pack a day habit started 3 years ago when he retired.He is inactive,sleeps to much,drinks coffee way to much.He did try the electronic? cigarette?That lasted about a week.
