I hope I don't linger, either. In fact, I wish it were as easy to put oneself "to sleep" like we can our pets instead of watching them suffer and hang on even when they wish they could let go. But nooooooooooo. It is against the law to die with dignity. Instead, you get shuffled off to some old folks home, amongst strangers, and die there...eventually.
Concerning Japan...I always thought they revered their elders. Becoming westernized sometimes is not such a good thing.
Some states allow this if the person requests it, and it is considered a medical, not a state issue, to the best of my knowledge. After her fourth bout with chemotherapy, one of my friends in Wyoming made an appointment and planned her funeral to the last appointment the week she passed in hospice. She was tired of chemotherapy over a 5 year time parameter. She wanted no more of it. It left a big hole in my heart, but she was enthusiastic about not having to suffer any more, so I dealt with it as her decision and that my loss of a dear confidante was nothing compared to the pain and unhappiness she was experiencing. She was in her fifties, and had been a beloved teacher and friend to many in her lifetime. It was hard on her daughter, though, but I'm sure that as time passes, the good of her life will be celebrated for the victory that it was.
The unfortunate thing about Obamacare is the loss of state's rights, however. Some would consider my friend's death unacceptable, including some willing to endure pain and not die until nature did it for them. That should always be the guarantee--freedom of choice within the parameter of the person's state. If they don't like the state's methods, they should cross a border where state laws are more in keeping with their beliefs.
I don't want to die with a needle furnishing me an easy way out. I want to fight and beat pain and kick pain's butt. I consider it fun.
