Given that the humble handshake has, since the dawn of mankind, been the international method by which we greet strangers and friends, you’d think that most of us would have got the hang of it by now. But sadly, not.

“With handshakes, it’s the bad ones that linger in the memory,” says Mr Les Child, a choreographer and body language expert who’s worked with brands such as Louis Vuitton and Gucci and performance artists Mr Michael Clark and Mr Leigh Bowery. “It’s not too strong to say a bad handshake can be revolting and creepy.

Here are Mr Child’s top tips for a handshake that can be forgotten in a hurry.
