Smoking: The Good News and the Bad News (Harriet Hall)
http://www.sciencebasedmedicine.org/...-the-bad-news/ Two recent review studies have confirmed what we already knew about the dangers of smoking, the leading preventable cause of death. The bad news: smoking reduces life expectancy by 10 years. The good news: stopping by age 40 can restore 9 of those years. Stopping at any age improves life expectancy, but the benefits decrease as age increases.
