By A. Pawlowski – Today

At 101 years old, Dr. John Scharffenberg drives a red Toyota Prius and is a YouTube star, sharing healthy living tips he himself follows, like intermittent fasting and eating a plant-based diet.

The physician, who is an adjunct professor at Loma Linda University’s school of public health, travels the world to give lectures about living longer with simple lifestyle changes.

He was in Madagascar last summer, Europe in the fall and has been invited to talk in Las Vegas this year.
