Oh god i'm afraid to answer this one...
I always said til y our mid 20s you bounce.. after that it's more like splat.
I've splatted a lot.
Though ironically worst injuries were not falls - shattered leg (kicked by another horse while riding), spine/road rash, trampled, back and neck injuries among others... (ran over by horse), broken pinkie/hand requiring surgery and pins (horse bucked on longe in place as I was backing away total freak accident)
Left knee reinjured in a fall when I just landed wrong but initial injury was playing soccer in HS and never had it fully fixed (had 2 surg, need a third but shattered leg instead and had to cancel lol) and right knee back in 1998 when my horse tripped and went to his knees and when I went to tuck and roll I was already so close to the ground I fell over my knee...sideways (had the surg for that one and it's been rebuilt nicely lol).
So yeah, hm, no major fall injuries other than knees. Oh once I got a concussion. But get this - I fell off and landed square on my butt! Apparently I jarred my skull and tore the lining of my brain that attaches it to the skull and they had me on meds for swelling and anti-seizure meds. Only I could get the worst concussion ever w/o ever hitting my head lol! That was also ages ago.
I rode a LOT as a kid. Well hell still do. And have a lot of horses so i'm just used to it being an "occupational hazard" ;)
