Dear sirs,
I am in favour of opting out instead of the current opting in.
If there is no record of saying no, take what you want/need to save a life, at once. They are dead and have no further use for it. I do not understand the who-har about samples kept, if it helps medicine do it, as a believer I know where I am going when the Lord calls and I don't want Him asking me why I didn't help when I had the chance.
I have carried an organ donor card as long as they have been around.
I am also a blood donor and apparently the record holder in this region.
May God speak well of you,
and wishing you all the blessings of Christmas and Blessed New Year.
John Gunn.
