A handshake\xa0is a globally widespread, brief greeting\xa0or parting tradition\xa0in which two people grasp one of each other's hands, and in most cases, it is accompanied by a brief up-and-down movement of the grasped hands. Customs surrounding handshakes are specific to cultures. Different cultures may be more or less likely to shake hands, or there may be different customs about how or when to shake hands.[1][2][3]
