Nobel prize winning biophysicist Erwin Neher on how to age well, and the best ways to keep our bodies and minds from degenerating. Erwin Neher won the Nobel prize for medicine in 1991 along with Bert Sakmann, for their discovery of ion channels in cells. He's a director at the prestigious Max Planck Institute for Biophysical Chemistry in Göttingen, and is about to visit New Zealand as a judge for the 200 thousand dollar Ryman Prize awarded for the best idea or advance in the world that enhances quality of life for older people.
