Bumping fists may be a more hygienic greeting than shaking hands, experiments at Aberystwyth University have revealed.
Using rubber gloves and a thick layer of E. coli, scientists at the university exchanged handshakes, high-fives and fist-bumps.
Their results revealed the transfer of potentially disease-causing bacteria is highest during a handshake.
This was reduced by more than half in the high-five, with germ transfer a whopping 90% lower when bumping fists.
"People rarely think about the health implications of shaking hands. If the general public could be encouraged to fist-bump, there is genuine potential to reduce the spread of infectious diseases."
