Definitely mixed opinions on wine as a medicine. I have read a few things that say resveratrol is the key and you can get it without alcohol. I also read something interesting where a doctor commented that many of the people in the studies that don't drink, or at least say they don't, have had drinking problems (full disclosure - I have and now don't drink) and are prone to unhealthy behavior and/or have already done some damage from that behavior. I think there is something to that; a significant portion of the non drinkers I know (and knew even before I had my problems) quit drinking because of drinking trouble. There are also correlations with social behavior and socializing seems to help with lifespan. It's hard to tell what are causes are what are just likely common attributes because of the actual causes.
