Sanjay Sharma, from the University of London (United Kingdom), and colleagues report that gentle exercise can reduce the risks of dying from a heart attack by half, among people in their 50s and 60s. Proposing that adults enjoy a daily brisk walk of 25 minutes, the study authors submit that” exercise buys you three to seven additional years of life,” and may confer effects on mood and cognitive skills as well.
