Everyone should have the right to determine that their quality of life is no longer tolerable and have a dignified end of life.
The only alternatives are a one way trip to Dignitas in Switzerland or the very difficult path of suicide which can be both painful and unsuccessful .
Please don't let people keep suffering for no good reason
Don't confuse length of life with quality of life .
I have Multiple Sclerosis and fully intend ending my life when it becomes intolerable to me. Each persons tolerance will be different and it should be totally down to that Humans Right to choose.
