We all try to fight it: the inexorable march of time. The fountain of youth doesn’t exist, and all those wrinkle creams can’t help. But modern science is giving us new weapons in the fight against aging. So how far are we willing to go? Hear when aging begins, a summary of the latest biotech research, and how a lab full of youthful worms might help humans stay healthy. Also, a geneticist who takes a radical approach: collect the DNA that codes for longevity and restructure our genome. He finds inspiration – and perhaps genes as well – in the bi-centenarian bowhead whale. But what if age really is mind over matter? A psychologist’s extraordinary thought experiment with septuagenarian men turns back the clock 20 years. Will it work on diseases such as cancer as well?  Guests: Gordon Lithgow – Geneticist, Buck Institute for Research on Aging, Novato, California Manish Chamoli – Post-doctoral researcher, Buck Institute for Research on Aging George Church – Professor of Genetics, Harvard Medical School, author of Regenesis: How Synthetic Biology Will Reinvent Nature and Ourselves Ellen Langer – Professor of Psychology, Harvard University and author of Counterclockwise: Mindful Health and the Power of Possibility First released April 6, 2015.
