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.
