We've long thought that aging was just a part of life but now science is beginning to view aging as a disease that can be treated. This, as research on aging is exploding and some scientists speculate people could live 150 years or more.  Our aging expert, Dr. Kristin Slade, Associate Professor of Chemistry at Hobart and William Smith Colleges in upstate New York says, "We already know what is going on with aging at the people level, but I was determined to get inside the cell and discover what was going on at the molecular level.” Indeed, that could be the key to slowing down the aging process. She spoke before an audience at the Conference Center in Mountain Village, Colorado and the discussion was moderated by noted journalists Judy Muller and George Lewis.
