People have mentioned old people with rickets and children in leg irons. Back in the fifties I was in hospital for a year, most of the time 'attached' to my bed. I was lucky, I wasn't in a 'plaster bed' like the person in this post http://margueriteheptonhospital.blogspot.co.uk/2009/10/colin-welbournes-further-recollections.html., but some of my friends were encased in plaster from head to foot.
Some of my fellow ward inmates spent years there, with their parents and relatives only allowed to visit weekends. Siblings under the age of 14 weren't allowed to visit at all. Children spent most days outdoors, even when it was snowing, sometimes sleeping outdoors, and the hospital was between a remand home and an open prison! I can't imagine parents of today letting their children live under the conditions that I and many more children in the past had to cope with. My account of my time at the hospital is here http://margueriteheptonhospital.blogspot.co.uk/2012/10/patricia-senior-nee-tasker-recalls-her.html
