generally:
the longer you are on, harder it is to get off
more we are old, more it is harder to get off
and there is also a genetic individual thing, for some it is harder, for other less,
i think it depends also what nerves(receptors/emettors) have been destroyed, it is random, so some have memory more destroyed, other walking ability, other vertigo,
we find these IDEAS in work of David HEALY
Yes, i only recently have moments where i am really better, and nothing is won
i had and have no choice, only one path to walk
