This is quite lovely. I very much enjoyed how you juxtapose the Doctor's and Vasta's acceptance of aging and old age against Jenny's genetically-human viewpoint that youth (and therefore reproductive capacity as pointed out in her reference to menopause being coupled with senility). I'm fascinated by the/whether there is a provable link between sexual selection/drive to reproduce and Western cultures obsession with youth/discomfort around if not abhorrence of the elderly. It was wonderful seeing two non-humans say "Getting old? BFD!" Thanks for including it in there.
