For the few people in any doubt, the risks of smoking carry on into later life and quitting smoking will help you to live longer no matter when you give up.
A large scale study conducted by the National Institutes of Health in America of more than 7,000 people over 65 concluded that smokers were about twice as likely to die from cardiovascular disease than non smokers and two and a half times more likely to die of cancer.
The good news was that as soon as someone quit smoking their risks of heart attack or stroke diminished to the level of the never smokers, although their cancer risks remained the same as before even after they'd stopped.
