Am i the only one horrified by smoking??????

Nope im dead against it my dad has emphazema, chronic bronchitis, has to have an oxygen tank whereever he goes, lost his taste buds, gets, gray in complexion,has had 2 heart attacks,and now has to have a 2 way heart byp all because he smokes or did until 3 weeks ago when the doctor told him that if he had the byp and didnt quit smoking he would die right there on the operating table and if he didnt quit and didnt have the operation he would only live another 3 to 5 years because his lungs and heart is so weak from smoking but it took the doctor telling him that before my dad would quit he went from smoking 5 packs a day to none at all in just 3 weeks and it really hasnt bothered him much
