In regard to the sisters and their health problems, I think that most of the time they were so busy caring for their charges, that their own health took second place.
The fact that Sister Edith never sought medical help, and tried to ease her discomfort by sucking mints until her condition became an emergency,showed her stoicism and dedication. It was also foolhardy, and makes me wonder whether the NCH ever required their staff to undergo regular medical check ups. Sister Edith's perforated ulcer could so easily have resulted in her premature demise. Luckily for all her Hartley family at the time and her much loved old boys and girls like yourself, she lived on into her nineties. T
That particular generation of sisters was cast into a stern and unsentimental mould. Their motto seemed to be, when difficulties come your way, face up to them without moaning and just keep on going. There's one thing for certain, they don't make them like that anymore!
