Worst incident was just toodling along at a casual pace on a trail ride. Clipped a pedal on a rock, OTB'd, bike landed on top of my chest, hard. I knew I was in a bad way but had to walk out alone, thankfully down a gentle slope. Got driven to ED, walked in, nurse took one look at me and put me straight into the resuscitation cubicle. Passed out. First catscan showed broken 1st rib (apparently only happens in high speed motor vehicle accidents), broken shoulder, broken collar bone, broken sternum, numerous other broken ribs and a punctured and partially collapsed lung. Two more catscans later (yeah, three fkn catscans, grrr) and they still couldn't decide if I'd dissected my aorta. Had to wait four hours for another test while I contemplated the possibility of being helicoptered to another hospital for emergency open heart surgery or possibly dying while I waited. Did some serious soul searching imagining my 2 year old growing up without a Dad. Got the all clear, phew. A week lying in a hospital bed on drugs, 6 weeks at home on drugs.
