NEW YORK (Reuters) - Ditching handshakes in favor of more informal fist bumps could help cut down on the spread of bacteria and illnesses, according to a study released on Monday.
The study in the American Journal of Infection Control found that fist bumps, where two people briefly press the top of their closed fists together, transferred about 90 percent less bacteria than handshakes.
