Now it turns out that you can sign up with an online registry to donate your organs postmortem. Not only does it mean that you don't have to worry about the little pink dot so much, it also means that you can do it without necessarily needing the permission of any other human being. My family was fine with it, but I figure it was worth pointing out in any case, since not everybody may have known that.
Anyway, yeah, I approve. This is the kind of thing that ubiquitous online access should do for us as a civilization - rather like the national "do not call" registry.
