The Definitive Book of Body Languagerestricting his right hand. Sometimes called the 'politician's
handshake', the initiator of the Double-Hander tries to give
the impression he is trustworthy and honest, but when it's
used on a person he's just met, it can have the reverse effect
leaving the receiver feeling suspicious about the initiator's
intentions. The Double-Hander is like a miniature hug and is
acceptable only in circumstances where a hug could also be
acceptable.'You're a lovable, memorable person -
whoever you are...'Ninety per cent of humans are born with the ability to throw
the right arm in front of the body - known as an over-arm
blow - for basic self-defence. The Double-Hander restricts this
defence capability, which is why it should never be used in
greetings where a personal bond doesn't exist with the other
person. It should be used only where an emotional bond
already exists, such as when meeting an old friend. In these cir-
cumstances, self-defence is not an issue so the handshake is
perceived as genuine.
