Lately there has been tons of research done in regards to coffee actually having 
long term health benefits. You'd be surprised to see that researchers have 
actually found significant proof of coffee having health benefits. In a huge 
study done among four hundred thousand people between the ages of 51 and 70, it 
was found that those who had coffee regularly were 10 to 13 percent less likely 
to have died over a thirteen year span.
