How do you greet your friends?

A nudge, a hug, even a high five - how do you greet your friends? Whatever it is, researchers at Aberystwyth University don't recommend a handshake.

They say it passes on 90% more germs than fist bumping - the greeting made famous by President Obama and his wife Michelle, after he was made US President.

And a hand shake was about twice as unygenic as a high-five, the study found.
