Real reason so many people have this exact same scar
If you grew up in a certain generation, there’s a good chance you have one — a small, circular scar high on your upper arm that you may have wondered about at some point.
For many people, it’s been there for as long as they can remember. But why?
I have a clear memory of noticing a distinctive scar on my mother’s arm when I was a child. It sat high up, close to her shoulder, and looked almost like a ring of tiny indentations surrounding a larger dip in the skin.
For some reason, it fascinated me.
I can’t remember exactly why I noticed it, or whether I ever asked my mother about it. Perhaps I did. If she explained it to me, however, the answer clearly wasn’t important enough for my childhood brain to remember.
Years later, I spotted the exact same kind of scar on an elderly woman as I helped her off a train. There it was again — high on the upper arm, looking almost identical to the mark I’d seen on my mother.
