I loved swimming. I was a swimmer and as an adult, I taught swimming classes. I was great at it. Then I started losing my hair. I went bald really quickly. I have Alopecia Universalis. For about a year, I taught swimming with a wig on. Most of the instruction was simple enough that I didn't have to demonstrate for the kids. I chose a stellar student and had him demonstrate.
I wore a really cheap artificial wig. It fooled everyone. I didn't have to deal with comments on my health. I could focus on teaching. However, it was annoying. I wanted to feel the water going through my hair as I was underwater and that didn't happen. It didn't happen because I didn't have hair.
So, I quit. It wasn't an easy job. I was cold most of time time wearing a bathing suit and standing in the water instructing kids. But I kind of wish that I had the confidence when I was teaching to go without my wig. It is tough when you've lived with hair for 33 years and suddenly you are adjusting to life without hair.
