(1) Could it not be vice versa, namely that many grandchildren are the reason for keeping old women longer fit?
No. (Because of natural selection/ "survival of the fittest". This is EVOLUTIONARY science). And if this "grandchildren keep grannies fit" thing would be true, other mammals with many grandchildren would exhibit post-reproductional longevity as well. but they dont.
