LOL... I had one brother that loved to fall from trees, three times as I recall, but he always seemed to grab a branch on the way down and broke his fall! Never was badly hurt. One other brother fell once, but not hurt and only from about 9ft.
I was very cautious about the way I climbed, what I trusted, and concentrated sufficiently that I never had the falling experience... even though I was the undisputed champion of the neighorhood. LOL
At my age, I still enjoy climbing trees... laugh if you like!
