Kissing was originally invented to make sure the other person didn’t have a sword in their mouth— Ryan Pequin (@ryanpequin) April 2, 2019
Shaking hands with a woman is like shaking hands with a child. It seems artificial and vaguely patronizing. The handshake was designed as a greeting between men to show that your sword hand was empty.— RAMZPAUL (@ramzpaul) April 1, 2019
BTW, History.com says:
While the handshake had several meanings in the ancient world, its use as an everyday greeting is a more recent phenomenon. Some historians believe it was popularized by the 17th century Quakers, who viewed a simple handclasp as a more egalitarian alternative to bowing or tipping a hat.
