I noticed a strange phenomenon the other day though, well it's been a few weeks back.
It was raining, and I had taken a wrong turn and was trying to catch up with my bud, knew there was a down tree up ahead and it'd be slick, but I hit it 3rd pinned anyway, over the bars, bruised hip/rib from clipping the bars and did a perfect tuck and roll. I'm laying on the ground and normally I'd get right up before the bike died but something told me to lay there a minute. Seemed odd because I didn't hurt and I never did figure out why. It's still puzzling..
