Which, in layman's terms, boils down to the fact that you don't really know what exactly it is you are looking at with some of these studies, although they do have big numbers.

When you are looking at statistics like these, you're seeing a correlation (more caffeinated coffee associated with better survival) but the study has not proved that it's the caffeinated coffee causing the improvement.

As Karen says, we're not seeing harm demonstrated, so lucky Alex gets to keep his coffee. On the other had, my husband HATES coffee (except in the gravy I make for Swedish meatballs) so I am not about to suggest he take up coffee drinking.
