Back when I was just learning to ride, I practiced doing 'emergency dismounts' until I was blue in the face. Also the 'tuck n roll'. Guess that's what's always saved me from getting hurt bad.
I've only had two falls on my wild man, one he tripped up hill, wasn't bad at all, he actually tried to jump a ditch after that lol, he was so crazy and I was young. The last fall he tripped up while anxious about his pasture mate being far, we tripped over a ditch and somehow landed on the other side. My leg got stuck underneath him but he was such a good boy and lay still until help came. If I could change anything, I would've tried harder to get his attention, maybe stop and get off. We were all over the place
