I don't yet carry a donor card but I will, not sure I could agree to donating my eyes or those of my loved ones, I cant really explain why either, think its the irrational feeling that without them a person loses their identity, on the other hand, having worked with visually impaired children I know they would be a true gift.
My Nan many years ago had arranged to donate her body to medical research after my grandad had done so. Sadly she died one June and when we tried to fulfil her wishes we were refused because the universities had started their summer holidays and we were told the freezers would be too full!
As for Scottyland, its beautiful, lived in St.Andrews as a child, now regularly stay in Moffat, Loch Lomond etc. You gotta go, scotty people are fantastic and so welcoming!
