Generally speaking, it’s not a good thing when someone approaches you wearing a mask and holding a sharp object. But that’s exactly the situation I found myself in recently. And it was clear that this person was going to cause me pain and then take my money. But I stayed calm by thinking about refrigeration. And sure enough, very soon my time in the dentist’s chair was over.
What’s the connection between dentistry and refrigeration? Well, the dental hygienist who was cleaning my teeth was dressed up in near-hazmat attire. She had on gloves on her hands, goggles over her eyes, and a mask covering her mouth. The same went for the dentist when he came in to look me over after the hygienist was done. Let’s compare that to when I was a kid. I’d go to the dentist, and he would walk in, pry open my mouth, and start poking around. No mask, no goggles, no gloves. I am assuming he at least washed his hands first, but to be totally honest I really don’t even remember that for sure.
