Wash Dishes, Live Longer

Gretchen Reynolds in the New York Times sites 3 studies that attempt to measure just how much activity is needed to increase longevity.  The bottom line is that moderate exercise, like brisk walking, for 65 minutes per day is best for life expectancy.   Do not dispare, though, because even low exertion exercise like washing dishes will increase life by about 2 years.  Just think what vacuuming can do.  Makes me want to clean house.
