20 minutes
Of life gone for every cigarette smoked. Yikes! I still cannot believe there were ads in the 1940s that said, basically, cigarettes were good for you. A new study out of University College London found a pack of 20 cigarettes knocks 7 hours off a person’s life. Say you smoke 10 a day and quit on Jan. 1. By the end of the year, you’ve “earned back” 50 extra days. Now, that’s incredible motivation.
