nate khan and polio

I'm one of those people that's old enough to have known someone with polio, or at least someon who had polio. It's pretty amazing actually, to think that few younger than 40 would know anyone afflicted, given how prevalent it was until Jonas got busy in 1954. 1954 really isn't so long ago but history has a way of remembering in a rather peculiar fashion. Those of us who are older might recollect seeing the braces and crutches and remember being told polio was the reason, but fewer and fewer ever knew anyone as a person. Certainly at this point you would have to be in your 70s or very close to know anyone who got it as a like-aged peer, which pool, or swiming hole was suddenly off limits etc.
Mary and I discussed pnemonia and antibiotics just yesterday - it's amazing how long it took us to figure some things out and how suddenly things changed in the medical world.
