The thought of outlawing handshakes and making fist bumps mandatory for hospital employees might strike you as rather amusing. But in studies that attempt to quantify the transfer of potential pathogens via customary greetings such as handshakes, high-fives, and, yes, fist bumps, handshakes consistently transfer the most bacteria from one individual to another, as illustrated by this cornucopia of colonies that sprung up after 20 handshakes in one study. Fist bumps, in contrast, transfer the least, making them a smarter (and perhaps cooler) greeting for doctors and nurses to engage in.
