(HealthDayNews) -- Did you ever notice that people who have lots and lots of money never carry any?

According to the journal, Occupational Medicine, a survey of people who handled large amounts of paper currency showed that 59 percent had work-related injuries. Of these, half had neck and shoulder pain, and the same percentage suffered arm and wrist pain.
Doing anything repetitively can become painful.
