DWB: If it’s your time, it’s your time. No amount of worrying, freting, or appeasement will affect that.

Which is exactly why it’s a roll of the dice to rely on your offspring to care for you in your twilight years – for all you know, you could outlive them. Or you could die before ever needing such care. As pointed out by others here, leaving yourself to your own devices is also a crapshoot, but of a different sort. Either way, you literally bet your life on your future, and that of whatever family you have, unfolding in certain way.

Like I said, pick your poison.
