I intentionally left it open.
You keep talking about choice, but there's not really a choice being made. Suicide is always on the list of options, but very few would do it.
Waking up the next day isn't really a choice, it's just something that happens. "Well, I didn't die yesterday. We'll see what happens today." If you could will yourself dead by choice many of us that have been through depression would have died long ago, but it simply doesn't work that way.
I haven't experienced suicidal thoughts, so am the opposite of an expert here.
I can't pretend to understand your viewpoint. The difference between willing yourself dead, and having the mental motivation to do an action that results in suicide seems like a very fine distinction. If they are as different as you say, it sounds like a good thing.
See, suicide means you've got to do something to make your body stop working. It will lead to pain or serious discomfort. Suicidal people don't want to go through that, they just want to flip and switch and call it a life. It takes serious dedication to hurt yourself.
Shooting yourself in the head is (usually) near instant as far as we know, but people usually don't want to leave a mess--just a body.
And yeah, it's a great thing that we can't will ourselves dead. We'd have a lot of dead teenagers who would do it after their first breakup because of their underdeveloped hormones and coping strategies.
Unless you're suicidal I think there's really only one correct answer to your question.
I'm guessing @InnocentBystander is a miserable liar: when the day comes and they need diapers, they will probably keep choosing to die some other day, just like all the other people who use diapers continue to choose to die some other day.
If I told you that I am young now, and in 10 years I will be old so I prefer to kill myself then, would you believe me? Does it have any meaning at all if 10 years ago I wanted to die today, but today I clearly don't?
Are you contemplating suicide?
