It’s been a while since I’ve been out for a ride on a skateboard. Around 40 years, to be exact. Four whole decades.

I can attest that whatever they are called, "judo" rolls and falls will stay with you and absolutely save your life.
And they absolutely prevent injury, or at least being injured worse.
Sometimes when I'm clumsy or trip, I have just gone down gracefully/rolled and popped back up before they even knew I "fell".
Sensei survived a motorcycle accident, tucked his head and rolled, did several summer salts. I got hit from behind while on a bike - while flying thru the air towards the ditch at a funny angle, tuckedmy head and rolled from shoulder to opposite hip and slapped the ground to splay and stop the inertia (luckily one roll was enuf)
