I grew up on a street with Polio survivors. Two in wheelchairs and one on crutches, the house on the far end of the block was a care house or a place where they put these guys together as it was cheaper than hospice. This was in the 70's and I don't remember much about them, their living conditions, if they were family or anything like that. Just they they were invited to talk to the schools about Polio and why we had to get the shots.
This story, and people under 30 not knowing what a Polio survivor looks like, has been brought to you by the modern medical miracle of mass vaccinations.
