Psychologists at the University of Minnesota's Carlson School of Management have found that handling money can alleviate both physical and emotional pain. In one experiment, test subjects were found to feel less pain when their hands were dipped into scalding water after counting money. Lead author Kathleen Vohs said, "When people are reminded of money in a subtle manner by counting out hard currency, they experience painful situations as being not very painful. You could think about being able to charge yourself up before you encounter pain. When I used to run marathons, I would've maybe wanted to be reminded of money first."
