How important is food as a factor that influences longevity? No one knows for sure because the study of aging is a tricky thing. Scientists have several theories of aging that deal with everything from cell division to genetics to oxidative damage (or “rusting”), but none of these tells the whole story. There are too many pieces to the puzzle, diet included, for a definitive answer, but by studying those who seemingly defy aging we can glean some important clues. Bruce Grierson, award-winning social science journalist and author, explored the mystery of the 90-something track star, Canadian Olga Kotelko, in his book What Makes Olga Run? Join us as we discuss the various factors that influence the aging process, and consider what people really want and are willing to do as they approach their senior years.
