Postmodernist writer John Barth said, “More history is made by secret handshakes than by battles, bills and proclamations.” So how did the seemingly innocuous act of clasping hands with another become so powerful? Paleoanthropologist and stand-up comic Ella Al-Shamahi, a Muslim woman, avoided shaking hands, especially with men, until age 26. Now she embraces the gesture.

The human hand is a veritable petri dish of germs.

The handshake transfers bacteria and viruses from person to person quickly and efficiently. Without rigorous handwashing, the germs responsible for the common cold, for example, can live on hands for longer than three hours after a handshake – the influenza virus, for up to an hour. Simply replacing the handshake with a fist bump can reduce transmission by up to 90%. An elbow bump could eliminate the risk completely.

Nevertheless, the handshake, an ancient gesture, has endured the deadliest plagues in human history.
