As workers return to the office, friends meet up and religious services move from online to in person, people are asking the question: to shake hands or not to shake hands?When the coronavirus crisis first began, an event planning business in Kansas City began selling "I Shake Hands" stickers.The words were meant to make social situations easier."We didn't want the sticker to say, 'We Don't Shake Hands' because that is kind of off-putting," said John DeLeon, vice president of operations and sales at MTI Event in Kansas City."But if someone had the sticker on in that group, then that was the indication that it was OK."DeLeon added that those who did not want to shake hands with others could simply choose not to wear a sticker.The handshake has been around for centuries.A widely held belief is that it started as a way to show that a person was offering peace and not holding a hidden weapon.But hands have germs.Dr. Anthony Fauci is America's leading infectious disease expert.
