Poor guy. I can't blame him at all for wanting to die since he can't do anything himself. It sounds like he doesn't really have anything to live for, so why bother? He seems content with the life he's lived so far and is ready to peace out at his will.

It sucks that people don't hesitate to euthanize a pet when it's terminally ill or in constant pain, yet many think this option should not be available to humans.
