I’m so sorry to hear about your friend, but what they did is really amazing.
Medical science really needs donations of bodies to help research. It can make a huge difference and aid medical advances and understanding.
I am on the organ donor register, but if my organs can’t be used after I die I would like my body to be used to help medical science.
I think the same as Suzi about this. I have recently had my will changed to say explicitly that I want my organs to be donated for transplant if they can be, and, if they can’t, then my body should be used for medical research.
