If my heart/lungs/corneas/kidneys/whatever, can help someone else live a better life, then it's a very easy thing to do.
The poll will only work for people with a DW account (I may well renew my LF paid account as well, but there's reasons why I don't want to do that for a few weeks yet).
If you're only on LJ, feel free to comment in the replies.
Do you carry a donor card in your purse/wallet?
If you wish to be a donor, have you told friends and family?
If you're not carrying a donor card, are you likely to get one in the future?
I know people who don't donate for various reasons - it doesn't mean you're a bad person, if you feel squeamish about someone cutting up your body after you're dead. Nor does it make you bad, if you're scared that the life support will be turned off earlier than you might wish. I'm okay with both of these, but that doesn't mean that everyone else is.
