As a dutch guy i only could say that the question is a bit different then the american guy say's.
In Holland people can get euthanasie when the suffer an illnes wich will lead to death. And they must ask for it, and a family member must also agree with it. And not all the docters would cooperate with the ill people. So you must go a long way before you can get euthanisia if you want it.
The other solution is to through yourself in front off a train, from a building. But then you hurt other people. We think euthanasie is a decent kind off way to end your life on a human way.
