I think it is messed up that so many people are not organ donors. Most of their reasons are just ridiculous. They'll say they don't know how, they haven't gotten around to it, they are not super young and healthy so their organs are no good, they want to be fully intact when they are chucked into a casket for years of rotting... argh!
I am a registered organ donor, but I'd like to donate everything... blood, organs, skin, eyes, hair, etc. Anything that can be used, they should use it... just cremate me after. I think they let the family decide about hair and eyes and other external things, so my family better be listening to me when I tell them I want to donate everything and be cremated.
