My physicals which left the strongest impressions on me were annual school physical exams, which were conducted in a trailer fitted out as a mobile exam facility. This was brought to the parking lot at our school, and we were brought out to the trailer in small groups of four or five at a time. We'd see the doctor, always a female, one at a time, while the others waited in the small first room. We'd either undress down to underpants or just completely naked. I always had such exciting thoughts knowing my classmates were either being examined naked on the other side of that thin wall, or that they were just waiting on the other side while I was being examined.
I remember when the trailer was there, usually for about a week or so, I could see it from the playground, so there was always the anticipation in the time before my own exam, and then the excitement of the memory in the days afterwards, too, which were invoked every time I was outside. It was always a very anxious week.
I still see such mobile medical facilities, in places all over the world, and every time it brings back those feelings of butterflies and tingles. There was one year when the doctor told me to undress, to take off everything except my socks. For some reason I felt more exposed that time than the times when I was totally naked, and that feeling has always stayed with me ever since if I'm wearing only socks.
Very fond memories, and I'm grateful that had been my experience, because I know seeing the doctor wasn't always so positive for everyone at that age.
