I went bowling today and after a few sets I forgot my form. I kept trying to remember how I approached the line and how I was swinging before, even what foot I put forth first but I couldn't do it. I kept messing up my form.
This is not the first time that this has happened. There was another time that I was doing something physically active and after a while of repeating the motion I forgot how to do what I was doing. Though I had been doing the same motion repeatedly, I forgot after the seventh, or something like that, time and just kept messing up afterward.
It almost feels like I never learned how to do it in the first place, my mind sort of goes blank and I can't get my body to function properly again.
What is this?
