Give me the freedom to end my life when I want to end it and you don't have to care about my care and I bet I am not the only one.
Can you guarantee that you will feel the same as your mobility becomes more and more restricted? Do you think that your current resolve is correct for everyone around you, and should be generally mandated? I agree to a reluctance to rely upon others, in the face of infirmity, but will I have the courage to forego that reliance in euthasia? I don't know.
As compared to be stuck on a bed in your own filth while your body is developing lesions on the back because you can't move? It is basically state sanctioned scaphism. Give me a ticket out of this hell hole.
