I believe that those who have life limiting illnesses have the right to die when they want to.
Tony cannot do it himself, locked in syndrome means he can't move AT ALL, how fair is it that he has no choice but to live like this until he dies 'naturally'.
My Mum has Motor Neurone Disease, she can choose to end her life when she wants to, watching her die by degrees is horrible, since November last year she has virtually lost her voice, she's due to have a PEG fitted so she can get nutrition straight into her stomach because her throat muscles are bad.
Her muscles will waste away until she can no longer lift her arms or legs, but her mind will be as active as ever, there will be a point where she will have to have a tracheostamy (?) to help her breath.
There is no cure for this horrific disease, eventually she will end up like Tony, but she will die regardless.
Why shouldn't people have the right to choose when THEY want to die?
If you are able bodied and suicidal you can end your own life, you aren't 'of sound mind' when you try.
DIGNITY is what it about.
