Be Dumb, Live Long

I don't know how one measures the intelligence of a fly, but apparently the dumber a fly is, the longer its lifespan.

Scientists Tadeusz Kawecki and Joep Burger at the University of Lausanne said Wednesday they had discovered a "negative correlation between an improvement in a fly's mental capacity and its longevity".

I don't know if this applies to humans or not, but it seems to have worked for Robert Byrd. Patty Murray will probably live forever.
