So, what’s their secret? And what else can we learn from their peculiar biology? From caves in Thailand and Texas to labs around the globe, the films meets the scientists who are decoding the superpowers of the bat.

The episode is a journey through the human gut and the process of turning food into energy to keep the body going. Humans have turned eating into culture, a way to celebrate our roots, to bring us together. But food is really just one thing: Fuel. It's where you get the power to live your life.
