A friend of mine, who is 65 years old, has smoked since he was a teenager and swears he was just pronounced "healthy" by his doctor. He also consumes an amazing amount of coffee during the day - and these two facts might just be linked.

People that drink a significant amount of coffee reportedly have less heart disease and liver damage than those that don't drink it. The article also says that coffee may help asthma sufferers, stop headaches, boost people's moods - and prevent cavities (?)
