Exercise Makes the Aging Heart More Youthful

For lifelong heart health, start exercising early in life and keep exercising often — ideally, at least four times a week, according to a remarkable series of recent studies involving hundreds of people and their hearts.

"Exercise Makes the Aging Heart More Youthful" is from the July 30, 2018 Science section of The New York Times. It was written by Gretchen Reynolds and narrated by Keith Sellon-Wright.
