(In the UK only 13 people out of every million end up donating organs, in spite of the fact that 90 per cent of the UK population support organ donation. One of the reasons it's so low is only 29 per cent actually carry a donor card and in addition in the UK, even if someone carries a donor card, their family can stop organs being used. So, an opt out scheme is being discussed, whereby you would have to register not to become a donor.)
