1. I signed up when I was 11. I asked my parents if I could be a donor, they filled out the form for me, and sent it away. I upgraded my details a few years ago, and have carried my donor card with me ever since. I plan on getting a small tattoo on my chest stating that I am an organ donor, just in case I lose my card.
2. I am donating all organs, including corneas, as well as blood, bone, muscle, valves, arteries, skin, and anything else that might be needed. Skin can be very beneficial in helping people who have suffered severe burns. There isn't likely to be much left of me afterward, but why care - I will be dead.
3. Not necessarily compulsory - that would mean that people with blood disorders and other illnesses would be forced to donate.
4. Yes, it should be opt out. Upon your 18th birthday, everyone should be presumed a donor, if you wish to take your name off the register, you should fill out the form, just as you do to become a donor. Having an opt out system would mean that more people would donate, given that most people wouldn't go to the trouble of filling out forms to remove themselves from the list. More donors means more people would live.
5. Family members should butt out, and have no say in the matter at all. Under our current laws, if a family member objects, the deceased, despite being a donor, will not be permitted to donate.
6. Yes, I do. Within reason. I don't believe that someone should have the right to decide that they don't want their organs to go to a Muslim, or a liberal, for example. But if someone didn't want their liver to go to an alcoholic, I think that is acceptable. My organs are healthy, and I take care of them. The way I see it, I should have the right to decide where my organs go, and I don't want them going to someone who has abused their body through alcohol or smokes, to use those vices as an example.
Obviously this is currently impossible, but its wishful thinking.
7. It sounds harsh, but yes, I do. Excluding those who suffer from an illness that prevents them from donating, or religious beliefs, if someone refuses to donate because of a petty reason, for example - 'I don't want to be cut up' then that person should not be eligible to receive organs. I believe that in order to receive, one must give. I also believe that anyone who receives blood should, if they are able to, make a blood donation at least once to give back what they received.
