Drink to your health! Scientists report that a chemical in red wine may contribute to longer life. The chemical mimics an affect caused on the body due to calorie restriction. "The chemicals are designed to mimic the effect of a low-calorie diet, which is known to lengthen the life span of rodents. Scientists involved in the research say human life span could be extended by 30 percent if people respond to the chemicals the way rats and mice do to low calories." They think that this is a biological response to lean times that allowed animals to live long enough to reproduce.
