I won't tell the stories, but my ex-wife was worried that I might go bald (didn't) and then all of the scars on my head would show!
(I was well known at the local clinic for head injuries that required stitches.)
Back in the late sixties, a small (very small) town nearby installed 5 or six new street lights that were controlled by sensors, e.g. they would turn on when it got dark and off when it got light enough.
Well, we would drive over to the town with a powerful (for that era) flashlight and drive around the town and "turn off" all of the street lights and make the town completely dark for a few minutes.
My neurologist in ca (seven years ago) knew I was an amateur collector and asked to see some of my firearms so I would bring a different handgun to his office in my briefcase at each appointment.
