Thank goodness we now have some contributions from across the pond. It turns out that :
British researchers report that an alternative to the traditional handshake might spread far fewer germs around. In their experiments, the scientists found that clasping hands transferred about 10 times more germs from one person to the other than what is known as a fist bump. They suggest the more casual exchange might suffice as a cultural substitute for the firm gripping of hands. The findings are published in the August issue of the American Journal of Infection Control.
Maybe we should be examining patients with our fists then? Or eating our food with a clenched fist? Idiots.
