Medical ethics would not allow you to end your own life on purpose, however if you chose to donate your kidney you could risk ending your life to save a family member. I think that this has been shown on telly some time ago.
Whats the point of this site if you cannot ask what you are thinking about Mic, I would like to think if the choice was given to help a youngster that's the route I would go, but everyone has a right to think! do we?
