Respectfully, the solution is don't smoke, exercise, eat well, sleep, avoid stressors... These aren't easy problems but their solution isn't at the individual patient level and is a simple question of capital and political will.
The 'hope' envisages a product to temporize the solution while extracting large payments.
> ...avoid stressors...
Most stress is caused by a conflict between our expectations/motivations and the reality (everyone else's).
I had a really great egg for breakfast. This now means I will never eat anything else besides eggs.
Also, I realized that cars run better with oil changes every 3 months or 5,000 miles. Because shorter was better, we should all start changing oil daily.
The best player in the basketball game last week was over 7'4" tall. I guess I need to discourage anyone who isn't that tall from playing ever.
Do you see why banning smoking is a good idea?
My position is: do not ban (make illegal!) everything that has statistically significant risk for one's health (like smoking, alcohol, mountain climbing, spelunking, bike-riding, horse-riding, car racing, NFL...).
So no, I do not see why banning smoking altogether is a good idea (and no, I am not a smoker — I never was either). I can get behind increased health premiums or heavy taxation, banning smoking in communal spaces...
