My brother was supposed to wait around for a chest x-ray but after the first few hours decided that 'couldn't be bothered' and went home. A bit stupid considering that he hit the steering wheel... on account of him not wearing a seatbelt... which again seems a bit on the retarded side. Hmmm, I think there's a lesson to be learned here, kids.
Regardless, he's as okay as I suppose he's ever going to be. Which is good news... of a sort.
