Once you crash, say 30 - 40 times, you learn how to crash and often don't get hurt as bad
I agree 100%
And it's not a conscious learning event.
It becomes instinct that just takes over.
I got so practiced at crashing head first that I actually turn my head to the side before impact so I don't smash my face.
My eyes pinch shut hard and my head turns sideways in a microsecond.
I actually haven't pulled off that trick in over 20 years now, but I'm sure that my "muscle memory" still remembers what to do.
Adrenaline can do some magical things.
I remember talking to a freind that crashed his bike and was airborne for 10-20 feet.
He said it felt like he had five minutes to decide how he was going to land.
I remember when I got my first ebike a few years ago, I cracked my shins Hard on the pedals almost a dozen times in the first month or so, but I haven't hit my shins since then.
I have no idea what I'm doing differently, but my shins are fine now.
