How do you shake hands?

[Donovan]

Fun fact: handshaking began as a necessary preserver of life during the more violent ages of history. When men met on the road there was equal probability one would be a robber or a murderer. The practice of offering one's right hand, the usual sword wielding hand, in a gesture signifying "I am unarmed and mean no harm" gradually became the universal symbol of friendly greeting even as swords stopped being widely carried.
