Due to different life circumstances, I've had to think about what loss of abilities I'd accept before choosing to end my life. Generally, the line seems to be drawn more due to mental degregation than physical disability, but I can see either being a reason to end my life.

That said, the response is determining what I would live for. I have ideas on what kind of physical, mental, and economic capabilities I would want to continue to live. I haven't crossed that line yet and I don't see that happening any time soon.

Based on what you've said, it seems like you're closer to that line. I don't know what you're living for, but people generally live for something.
