A little drinky poo helps old people remember things.

Science Daily News reports that moderate alcohol consumption in seniors can improve memory for events.  Light drinkers had a larger hippocampus.  The hippocampus is a part of the brain that goes downhill in early-stage Alzheimer's disease.

This connects to another study reported this week showing that flavonols in chocolate and cocoa can reverse memory decline by affecting a different area, the dentate gyrus in the brain.  This reversal of age-related memory decline is different from the episode memory discussed above.  "A cup of cocoa, then bed, keeps you smart in the head".
