Mayo Clinic Says Too Much Coffee May Kill You

A study from our friends down in Rochester says that drinking more than four cups of coffee a day increases your risk of death by 50%. In the Courier Mail, researchers said that the evil effects of coffee's caffeine had the strongest effect on people under 55.

What's the big deal? According to the study, the caffeine in for increases the release of certain brain chemicals, inhibits insulin activity, and increases blood pressure.

Of course last month, a study showed that drinking four cups of coffee a day cut your risk of suicide in half.  Thanks science.

Once you make it to 55, caffeine doesn't seem to have the same effect.
