I went to the doctor today for my annual checkup. For once, I actually had a pretty solid mental list of ailments ready to rattle off so I wouldn't forget to address anything with her while I had the chance.
Toward the end of our chat, I mentioned a couple of warts that had been bugging me and resisting my efforts to make them go away. She casually said, "Oh, they're a virus and very common. Really, the surprising thing is that people aren't just covered with them all the time. And fungus, too."
From a scientific perspective, I found that quite fascinating. But a big part of my brain couldn't get beyond thinking, "Ewwww!"
