Michael puts his body to the test to help you at home understand yours, as he tracks down answers to lots of burning questions, such as; Why do we get creaky joints? What happens when we catch the flu? Can we help our brains stay fit as we age? How do doctors replace a hip? We meet people from around the country with stories to share that shed light on the hidden marvels of our bodies.
