I never had anything really major in over 40 years of cycling. The worse accident I had was some lady turned right in front me to park horizontally on a street sending my bike into the side of VW Beetle which threw the bike forward and put my helmeted head through the side window breaking it and then I bounced my head off the side pillar as I was being thrown onto the pavement dislocating my shoulder. And that's the only injury I got was the shoulder. Paramedics witnessed the accident because they were right across the street so they came over an transported me to the hospital so they could put my shoulder back in. My bike got destroyed so I got a new one from her insurance company.
There is some very good and unusual news that came out of that crash. I was commuting to work and was dressed in dress clothes for an interview for another position at the same company, I was suppose to be there at 1 pm for the appointment, no cell phones in those days so I couldn't call, I arrived to work at 4:45 pm and my future boss was leaving, so here I come into his office with my dress clothes all dirty, my arm is in a sling and I was very late. He looked at me and started yelling that I was late, I looked unprofessional, and some other stuff I don't recall, then without ever letting me speak he then says: "You got some balls coming into my office looking like that and late on top of it for the most important interview you could have had in your young life, if you got that kind of nerve you'll do well at this position, congratulations you're hired!", I shook his hand and he left, I was a bit stun needless to say, and all I could say was thank you. So I had a new job while going to college that I'm pretty sure I was the highest paid student at that college!
