yeah, man, that is harsh... but it's interesting we have sympatico and i also have had a brush with kidney failure as well
i didn't quite get to the point of totally crippled but i could hardly even manage more than climbing a few flights of stairs and i pushed myself really hard to just do 5-8 mile walks here on the island this last year... ok it's pretty hilly terrain but it still was hard and i pushed myself to do it anyway, because the alternative was being on some lame hardly ever bus timetable and i knew i needed the exercise
anyway, it's over the peak of the hill for me now, i'm starting to recover
