What's the most basic thing you can't do? - Lemmy

I used to be unable to jump, but then I did Morris dancing. I learned how to jump normally at 27.
What happened when you tried to jump? I can’t picture this.
I second the curiosity. What would it look like? Sudden crouching? Paralyzing indecision?
I’m picturing those seizure goats
