I rarely shake hands anymore. “I’m just getting over a cold.” If I do, it will be when departing and I can go wash my hands. I think we should forego the custom. Over the years, think how many hands we shook that weren’t washed after taking a leak. May as well go around shaking each others danglies.
I went to a doctor who came out of the restroom tucking it in and wanted to give me a shot without washing his hands.
