Many people have heard of him, even if they have never seen him.

Professional sportsman in possibly one of the most contactible of contact sports.

He had 'failing kidneys', was on dialysis, then was given a kidney, to be transplanted into him, by one of his friends.
Cured of his illness he went back into playing the sport he loves, where he could "possibly" injure himself and his new kidney. SOME people said he shouldnt do it and he should just be thankful he is once again healthy, calling for him to not play again.

It is his dream to play once more for his country that he loves in the sport that he loves, why should other people tell him what he can and cannot dream?.

I would personally love to see the guy again playing for the all blacks, if he was still good enough :P
