Reuters covered a large study from Taiwan’s National Health Research Institute (Wen, et al) today that shows dedicating even 15 minutes/day to a moderate form of exercise like brisk walking, will benefit anyone. Some people struggle to stick to the standard guideline of 30 minutes a day of exercise, five days a week. While that may be optimal, this study demonstrates consistency with just 15 min/day can make a significant difference. The study, which tracked 416,000 people over 13 years found an increase in life expectancy of three years compared with those who remained inactive.
