Wow, the importance of wearing a seatbelt. I had an uncle who actually died in a car crash because he flew out the windshield of his car going about 80MPH and flew out into the road, and then got hit in mid-air by a passing car. (This was on a highway; the car in front of him spun out [raining] and hit his car with its rear, sending him flying, and a car on the next lane hit him by accident.) If he had been wearing the seatbelt, he'd have probably had minor facial scarring.
Anyways, hope you get better soon. (35 is a tad young to retire though, ain't it?)
