There has been some debate here over euthanasia.
A woman, Nancy Crick committed suicide with drugs she bought over the 'net. She was diagnosed with terminal cancer and her bowel had been removed. She had tried hospital care / pain management but decided that her quality of life was not good enough.
Turns out she did not have more cancer, only an in-operable twisted bowel. (she had lost extreme amounts of weight and would have been in pain for the rest of her life)
In my home town someone commited suicide by rolling their wheelchair off the end of a public jetty. They had tried a few times before and had been refused the drugs needed.
It is well known in medical circles that fatal doses of medications are often given to paitents by medico's. It is just not talked about.
Another woman is asking to be allowed to commit suicide as she has motor neurone disease and soon will not be able to self administer. (In Australia not stopping someone commiting suicide is pretty much the same crime as manslaughter)
I have taken my pets, one that I grew up with for 15+ years, to the vet and had them put down. I did it because they could not 'enjoy' their life anymore. As much as it hurt me I could not see them suffer.
If we give this relief to a pet, why not the people we love?
