Coffee Contradictions

My ears perk up every time I hear about a new study on coffee. And for the past decade or so, I've heard or read a fair bit about the health effects of drinking coffee. It seems that they take turns in suggesting that coffee is good for you or bad for you. Yesterday and today, I read two more such articles. The first suggests that drinking coffee could make you crazy if you're young, and the second suggests that it will prevent you from going crazy if you're old. The contradictions continue. On the other hand, this might have explained my dad's enthusiasm for drinking coffee.
