Dr. Alexandre Marchac, guest in the show "Bienfait pour vous", relocated to Roland-Garros, explains the impact of sport on skin and health.

Athletes live better than people in the general population, says Dr. Marchac. Two and a half and five hours of exercise per week are huge benefits of occasional athletes, says the doctor. Like Winston Churchill, the exception is those who live a long time without doing sports, he says. "Sport is a fundamental component for healthy living and the last years of your life," he adds.
