The problem we all face is the human need for interaction, previously conducted through the handshake, and the need to listen to warnings from governments and public health officials calling the practice dangerous.
Research shows that, if someone tries to shake someone’s hand and the other person resists (for whatever the reason), it makes the first person feel uncomfortable. An awkward greeting where one or both parties exhibit uncertainty as how to act, can also have a negative effect and it can take time (which we don’t always have) to repair the damage.
We need certainty and the best possible behavior guidelines. It will involve new techniques, as demonstrated in the previous video, and new scripts.
