Do please wait until I'm not using them any more, but I'd like to put it on public record that at that point, I'd like my organs to be given to those who can still use them.
Australia has an opt in organ donation system; people aren't organ donors unless they've actively agreed to be. I've made sure that my loved ones know that I'd like to donate my organs when I'm dead, but it can't hurt to shout it from the roof tops. Even if only a dozen or so people can hear me if I shout from here.
If you're in Australia, you can register to be an organ donor too.
