Sanjay Gupta

Interested in learning a new skill in the new year? CNN chief medical correspondent Dr. Sanjay Gupta says that will also improve your brain health. "The act of experiencing something new — or even doing something that's typical for you, but in a different way — can all generate these new brain cells," says Gupta, a practicing neurosurgeon and associate professor of medicine at Emory University School of Medicine. He has a new book about the brain.

In his new book, Cheating Death: The Doctors and Medical Miracles that are Saving Lives Against All Odds, CNN's chief medical correspondent reveals the breakthroughs that can save even those closest to death.
