[Sin]

As athletes they're probably trained (like I was) to relax their body when they start crashing... that's what prevents the really serious injuries most of the time.

I was in an accident in an SUV with my friends last year and I was the only one who wasn't hurt, and I wasn't wearing my seatbelt (probably actually beneficial in this case) some of them were some of them weren't, but they were all "Oh god gonna crash" and tensed up & got hurt, for me its automatic now to just go completely limp.
