Yes. God forbid I or anyone close to me should ever be find ourselves in such a situation, but should it happen, the decision has already been made. I do not want to exist when I am no longer able to enjoy life or be a burden to anyone else.
That being said, I would not expect anyone to administer a lethal injection or concoction to bring about my death, for I could not be that person to do it to another.
I pray that a solution is around the corner and I don't have to fly to Switzerland, or wherever it is one must go for euthanasia.
Having read through some of the comments, I see that most people feel that the responsibility falls on the doctor. I'm not sure which doctor or where, I absolutely agree for this to be legal there has to be psychiatric evaluation involving a panel of medical professionals but I don't necessarily believe a doctor needs to be the one to terminate life. I reckon there would be few medical professionals willing to put their hands up to do that. I'm an RN and no way could I do it. I believe in it, and believe it's a persons right to access it, but couldn't bring myself to be the one delivering that service. I also don't feel that the hospital environment is a place for it. End of life decisions and care are difficult enough in existing situations.
