You're right. It would be an immense relief, for me and for my family too, because they know it's important to me. It would enable me to decide on the right time to leave. I'd prefer to go at the age of 80, of course, but I know that won't happen.
The one thing I'm afraid of is letting things go on for too long and get to the phase at which I can no longer give my consent. I'm afraid of being a prisoner in my body and having to do miserable things to myself to try and put an end to my life, which is something I don't want to do.
