You can get turned away from a trauma room??? Sorry, spoilt welfare-state'ee speaking. The thought hadn't crossed my mind.

Re being spoken for I carry my organ donor card, because it's important to me to convey that information fast, that I want to donate anything that can be used.

But yeah, rethinking I think the best reason for me to carry ID is plain courtesy for my family's sake, in case I'm in a coma and my injuries are life-threatening. It would make no difference to me but it would be better for them to be able to see me before I died.

Sorry for being morbid
