Besides being an odd way to tease me about my maiden name, this is a topic that has been on my mind lately. Being an organ donor is the kind of thing that makes a huge impact with no effect on your life. Think about it: by the time you are called to this duty, you will have been "called elsewhere".
Now, to be fair, it should be discussed with family and loved ones, but this decision rests with you alone, and frankly, it seems to be an easy one.
I just signed up online, and if anyone here is not a legally recognized donor, I suggest you sign up as well!
