If you're looking for a simple way to extend your life span, Dr. Oz says to look no further than your nearest hospital. Many offer hyperbaric oxygen therapy, a treatment Dr. Oz calls a potentially great longevity tool since it keeps stem cells healthier so they can repair our bodies.

While sports stars and celebrities have been getting oxygen therapy for years, Dr. Oz never tried it…until now! After an hour—the usual treatment time—Dr. Oz comes out of the chamber feeling more alert and jazzed up.

"It's a pretty cool feeling. It's like being in a sub, or if you're a scuba diver, that's what it feels like when you get pressurized," he says. "A lot of folks might equate it to being in a plane. Your ears begin to pop."
