On the subject of injuries, my dad was working on building a garage once when his nail gun ricocheted a shot into his hand. Claiming it was "not that bad" despite the blood running down his arm, he pulled out the nail and went back to work. Unfortunately my dad tends to get angry when he gets hurt rather than taking a step back to reassess the situation, so a short while later he had another ricochet, this time through his wrist (and involving quite a bit more blood). After much convincing from my mother we finally got him to go to the hospital and get the wounds taken care of, but he was still back out there working later that evening.
It's my perverse life goal to top that at some point.
So far my best is riding downhill around 25 mph on a bike in the middle of windstorm, a branch breaks off a tree and lands right in front of me with no time to stop. I *flew* like a fricken California Condor before landing on my left arm and rolling about 15 feet on pavement. My arm was swollen, in excruciating pain and I couldn't move it (I was pretty sure I broke something at the time). Never the less, being the stubborn idiot I am, I turned down two offers for a ride home claiming it was "not that bad", and rode my bike the remaining 6 miles home with one working arm in the middle of a windstorm.
I still couldn't move my arm the next day so after some convincing from coworkers I went to the doctor for xrays, amazingly it was just the worst sort of bruising have yet to endure (most of my arm muscles were totally wrecked). Apparently I'm pretty good at tucking and rolling in high speed collisions with mother nature, who I'm now fairly certain has it in for me.
Oh and for the record, that story is why helmets are manly. My head skipped off the pavement twice during the landing, and if I hadn't been wearing one I wouldn't have had the opportunity to be a stubborn jackass afterward
