As biogerontologist Aubrey de Grey's presentation at the University of Alberta grows near, the Gateway is running an overview of his views on the future of aging and rejuvenation research. "He has theorized that aging in humans is caused by molecular and cellular damage that accumulates in the body over time (the by-products of basic processes like digestion). By limiting the buildup of these by-products, which are only harmful to the body in high quantities, de Grey suspects people can thwart the aging process and live young, vibrant lives for thousands of years. Currently, scientists are working to find ways of making mice live far beyond their typical life expectancies. To speed up the process, de Grey helped establish [the Methuselah Mouse Prize], a cash award given to scientists who can engineer the oldest mice."
