Folks who are lean are more likely to fidget, stand up or pace
about than their moderately obese counterparts, according to
a study of 20 self-identified couch potatoes conducted by
researchers at the Mayo Clinic in Rochester, Minn. For 10 days
scientists measured their subjects' every movement, using
sensors embedded in specially designed underwear. The 10
lean participants were more active even after they were required
to gain weight. Fidgeting is good for you.
