I'm with Laticsfan on this one. If some SOB who is still alive can take advantage of this SOB's organs etc. I figure go for it. My gf has her card signed and I need to check if mine is signed. But more so for me I need to see if I can still do this after having had cancer. It seems to me that while I was once a blood doner I can't donate blood any more and that could also apply to organs as well. I think that even if I had some sort of slow acting cancer if any of my organs could extend someones life they should use them but they make look at it from the point of view (sadly) as the cost of the operation vs. using less than top of the line organs. Sadly it may not be considered cost effective.
And yes, letting your family/doctor know this is the case is important. Time on this matters is crutial so you don't want to be surprising people with this sort of news.
Think about it. If that was your parent, spouse, child, friend or whatever, and they were on death's door waiting for an organ transplant of somekind, wouldn't you be wondering what the hell was wrong with people who had died but didn't sign their card??
Lets face it, we do it with things like cars if it is possible, wreckers pull parts to keep other cars going, so if we'd be happy with doing that is it so hard to make the jump to this being OK with people, religious objections aside?
Oddly while not making one immortal, it would be OK to have part of me carrying on after the rest of me had stopped! Maybe I'd end up in a fellow Corvette driver!!!!
