Miss C's sister is an ogress!
My sister is 6 ft tall. One day she remarked upon the fact that we never see very tall elderly people. I have heard that tall men and large animals are wont to die earlier than smaller ones, but I did not wish to depress her, so I refrained from relaying this information to her. Besides, I am not sure if this is altogether true, as a general rule. Anyway, I said that people shrink with age and that probably explained why we don't see a lot of hulking old people stalking the streets. My sister said, "That's not true, tall old people just hide in their houses so they don't scare children!"
