To live longer, shop more, study suggests?

Retail therapy does more than soothe the soul — it could also be a sign of long life for elderly people, according to a new study.

Elderly people who shop every day are 27 percent less likely to die over a 10-year period than those who shop once a week, the study said. (The study was limited to Taiwanese, so the findings may not apply to all groups of people.)
