Answer 1

Answer:

It's become so ubiquitous that you may never have thought about why people shake hands. The history of the handshake dates back to the 5th century B.C. in Greece. It was a symbol of peace, showing that neither person was carrying a weapon. During the Roman era, the handshake was actually more of an arm grab.
