Sho Yano on getting an M.D. at 21 years old

He began college at age nine, medical school at 12. Now at the ripe old age of 21, Sho Yano is set to become the youngest graduate ever at the University of Chicago's Medical School when he receives his diploma this Saturday.

In fact, he's 2 years younger than most students when they enter medical school. And he's already received a Ph.D. in molecular genetics and cell biology under his belt.

Sho talks with Ashleigh Banfield live on "Early Start" this morning to talk about his remarkable achievement.
