""It was a great conference overall, but there was not enough emphasis on nutrition. Luckily, the main nutrition talk was by Dr. Klaper. Another great talk was the Caerphilly study which showed the importance of long-term lifetstyle interventions (like eating more fruits and vegetables) in improving morality."

I thought it was the healthywholegrains so beloved of Graham & Kellog that decreased the libido, and thus would, one assumes, improve morality. :-)
