Fist bumps less germy than handshakes, study says

The familiar knocking of knuckles spreads only one-twentieth the amount of bacteria that a handshake does, researchers report. That’s better than a high-five, which still passes along less than half the amount as a handshake. So fist bumps seem to be the wisest greeting, especially during cold and flu season, said researcher David Whitworth of Aberystwyth University in Wales.
