Some countries have what you call first person consent. And it's where you and only you, once you're past the age of 18, can leave your body to medical science. Other countries have what's generously called second person consent. This is where after your irritating aunt dies, you can donate her body on her behalf to medical charity. So it can be tempting for people who are short of money or aren't particularly interested in the person whose body they now find themselves in the care of as responsible for. In Britain, it's changing because we've got this new center called the National Repository Center in Nottingham. It reminded me a bit like the kind of chemistry labs men at school.
