I know the feeling with jumping up and getting back on quickly. Some friends and I went dirt riding at Richlands Furnace outside of Chilicothe a few years ago. Torrential rain all day had the trails soaked, muddy, and pooling with water. I resembled a dead fish smacking a river bank when I tucked the front down in the bottom of a deep valley creek bed, it was a hard impact and knew my shoulder was torn up as soon as i hit the ground. Everyone was asking if I was ok and how bad the crash looked. I jumped right up, quickly kickstarted the bike, and yelled lets get the hell outta here before the pain sets in! It ended up being a separated shoulder, and it didn't bother me much until after the long drive home, but I toughed it out long enough to unload the bike and nab a hot shower. Took a few weeks before it was healed up. That was the last time I rode in the dirt LOL
