firstly i cant stress enough how few people carry a donor card or at least discuss the options to family and friends..
there are certainly no way enough donor organs to accomodate all those who need them.
PLEASE AT LEAST THINK ABOUT IT
anyhow,i have heard in the past of people having donor organs then claiming to be in some ways different,obviously not just in health but in personality and odd traits they didnt have beforehand..often enough they believe this to be in some way part of the person whose life ended,but saved theirs coming through.
what are your views on this
