Zero. I've drunk alcohol in the past, just to be social (honestly I usually just accepted a glass, and took a token sip a couple times).

With what I've read and seen about the brain dulling effects of alcohol, I don't even want to accept the token glass anymore. I need every single brain cell I have. Nothing to spare for alcohol to destroy. Not to mention the other negative effects.

And the most recent research (I believe) on red wine is that there's really zero benefit. Not that I trust most of this kind of research.

Interesting tip - if you want to find the other side of the story, just put the word "myth" in your search string. For example, search for:
