World's Most Extraordinary People

Discovery (1x6)

:

In this episode, Weston uncovers the cases of an engineer who fixed his own heart, a toddler whose bones were repaired before he was even born, and a girl whose immune system attacked her own brain. We meet a man who can taste words and find out how his condition is helping develop new ways to enable blind people to navigate and even recognize colors. And we encounter a man who was immobilized by MS but can now cycle and scuba-dive thanks to a pioneering new treatment that has reversed his disease.
