Lot's of us carry an organ donor card, so when we die, our organs can be harvested & donated to someone, requiring an organ to carry on living

Nowadays you can donate a living kidney whilst you are still alive

That way you know your kidney is going to help someone

The only trouble donating a living kidney it is anonymous

But there is a website where you can register as a potential donor and potential recipients register too

You can find someone who is a match; either potential donor/recipient and arrange to meet as a match & the donation to take place

I actually met a guy in the US & we were a match

But the US CBP would not let me enter the UK with a criminal record

If the guy had have been well enough to travel here that would have solved the problem & the transfer could have gone ahead

But US CBP said no
