This is for me. I have decided that I want to donate mine (or any part of it that might be useful) when I am done with it. Even though I expect to continue to need it for many years I want to start looking into it.
My husband donated his brain for dementia research so I'm not entirely new to the concept, but I've only recently made this decision for myself. It would be good to hear from someone who has handled this for a loved one.
