Living to 100 isn’t as hard as you think it is. In fact, a doctor thinks she has identified specific steps you can take today to reach the century mark.

Dr. Alexa Fleckenstein and award-winning medical researcher Roanne Weisman talked with Growing Bolder about their new book, “Healthy to 100: Aging with Vigor and Grace,” and they identified five ways to prolong your life.

Plus, Dr. Fleckenstein gives advice to everyone who has ever been told by a medical professional that his or her course of treatment was the only option.

She says you have to listen to your own body and YOU need to be the sole person to make decisions about your health.
