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:
