Self-termination is sometimes referred to as "a permanent solution to a temporary problem." This idea resonates with many as being true at some level, however a terminal-illness can be regarded as different, i.e. not a temporary problem. If there is not a terminal illness in the equation, would you agree that the situation tends towards the idea of "temporary problem/permanent solution"? If there is not a terminal illness in the equation, is there any sort of condition or threshold you believe should exist to deprive a human being this "right" under any condition? For example: should a human who does not have a terminal illness and has not yet reached majority age, have the "right" to self-terminate? Why or why not?
