A shop a day keeps the doctor away?

So "retail therapy" actually can work then?  A survey of over-65s in Taiwan found that those who shopped every day lived longer than those who didn't.  Could be just coincidence of course, but the point is made that shopping involves contact with other people, physical exercise and at least a degree of mental stimulation, all of which are considered beneficial to health.  Unusually for a man it seems, I like shopping, though I certainly don't do it every day - still, that's got to be good news, hasn't it?
