Friday night I got blindsided by a taxi running a red light here in Changwon. Totaled my bike, and I'm in the hospital until monday for observation. Mostly just bumps and bruises, some abrasions, but there also the fact that my helmet was broken in about a dozen places. Given the way it was broken, and given the way I slammed into the taxi (taking out his windshield in the process), this much is true: without it I'd either be dead or have a debilitating brain injury. As it is they kept me here under observation for a few days to make sure I didn't have an intracranial hematoma on my occipital lobe (initial CT scan was inconclusive). So far so good.
When I get out of here I'll borrow my girlfriend's digital camera to photograph the helmet in question. It has assumed a general sort of distorted shape that a canteloupe might have were an elephant to trod upon it lightly.
TL;DR version: WEAR YOUR ****ING HELMET.
