Dr. Jeremy Jacobs of the Hadassah Hebrew University Medical Center wrote a report in the Archives of Internal Medicine that it is never too late to start a fitness and exercise program: "Physical Activity, Function, and Longevity Among the Very Old.' "
Previously sedentary 85-year old individuals were put on a 4 hour per week fitness program. Their 3-year survival rate was double that of inactive 85-year old individuals.
The 4-hours of activity does not have to be done all at once. A 15-minute stroll a few times a day is sufficient to show a physical fitness benefit as long as it totals to, at least, 4-hours per week of activity.
