Quit Smoking Commercials Cigarettes

How many smokers out there over 65 years and how do you know??
I remember a lot of very old men of my childhood is dead old age of 70 or 80. I know a little bit now. I've seen old men in households outside smoking in wheelchairs there. Could the effects of smoking ciggaretts be distorted if the government can tax? The truth ads are bad numbers, they do not take into account the number of people who have died had they not smoked. Many people die of lung cancer and heart disease who have never touched a cigarette. It is as if they smoked and smoking is the cause?? Why this deception?? I'm not an idiot and I know I need to stop, but I do not think its bad as they say. Any comments??
My grandmother smoked for 77 years and the only reason she left because my aunt is taking care of her not share CIGARETTES more. Also because she is 95 and too old to remember her smoking.
