AWESOME
racechik - though extremely admirable what you want to do, I can only cringe thinking it may risk YOUR life in the future.
I too, would do most anything for a friend or two in my life - but at what risk. And I have to guess he would not want you in harms way either - imagine he lives after the transplant and your cancer comes back and because what you did......
think it over, talk it over deeply with him considering all the possible outcomes. Decide together.
It is a thrill to know people as selfless as you still exist.
Bless you and best of luck to your friend also
