Here’s my little theory:
Millions of years of evolution, since way before human beings even existed, have instilled an innate instinct for self-preservation in our ancestors, and by extension, us.
This likely includes avoiding nosediving off a higher elevation straight into the ground for no good reason.
So when you’re up there, your frontal cortex is engaged in a brutal war with your lizard brain. It’s pleading it’s case through logic: you’re on a skateboard, it rolls, and you will be perfectly fine as long as you commit. Meanwhile the primitive part is like “no, fuck that, you’re not supposed to throw all your weight down towards the ground, you’re going to get us hurt”.
When you think about all the eons of programming you’re trying to override, it’s almost a miracle anyone ever learns to drop in at all.
A hella testament to the power of the human spirit, know what I mean?
