I totally respect your choice, for its a matter of personal preferences but you are a very sensible posters (full of wisdom) so I would atleast ask you to revisit point A) and B) of your reasoning. Point A, well you are right, its God’s gift to us but we are all creatures of God and so it stays this way. Regarding B, I guess niksik or anyone who has worked in this field can tell you more if your concern is still valid with the advancement of organ transplantation.
