Alcohol

Results, published on line at the International Journal of Cancer, link alcohol consumption to an increased risk of colon cancer. Participants in the study who reported consuming three or more alcoholic drinks per day had a 26 percent higher lifetime risk of colon cancers than non-drinkers.

The list is quite long of the kinds of problems you can get from over consumption of alcohol such as: loss of memory, becoming violent, becoming fat, liver damage, slurred speech, lack of tact in social situations, coordination problems etc.

But life would be so dull without our alcohol!
