I was having drinks with a friend the other night. Frank is fully twenty-three years older than me, putting him in his mid-eighties. A retired professor and writer, he’s good company.

So it wasn’t surprising that we were ribbing each other and laughing when he suddenly sneezed and loudly farted. My reaction was to ask, “Frank, are you all right?”

“You notice that?” he said. “I did four things simultaneously.”

Before I could think more or speak, he said, “I laughed, sneezed, farted, and peed all at the same time. Now that’s multi-tasking.” Standing, he added, “Excuse me. I need to go to the restroom.”
