In 2015, while walking with my wife, Jody, in our neighborhood, I suddenly found myself bent over and taking tiny, rapid, repetitive steps. I knew I was moving too fast, but could not stop myself. Jody thought I was kidding—until the moment I fell down on a neighbor’s lawn.

A passing driver slowed down to ask if I was okay. I was all right, but thought the experience odd.

I’d never heard the word “festination” (a walking gait characterized by involuntary acceleration) until I saw a neurologist friend a week later.
