Survival of the Sickest: The Surprising Connections Between Disease and Longevity

Guest: Sharon Moalem, Ph.D.

Today on Focus, Dr. Sharon Moalem talks about how many of today's diseases may actually have been beneficial to our ancestors in the long run. In her recent book Survival of the Sickest, she explores how we perceive our bodies, our health, and our relationship to other living things, and how little modern medicine may understand about human health.
