One of my undergrad profs had polio, she was great. I did not realise how recent it was an issue until I saw a video and they showed this woman that is still in an iron lung since getting it as a kid, that has to be horrible! My dad remembers a friend of his getting it and his mom not letting him even talk to the kid on the phone because she was scared he'd get it, those were scary times, thank goodness for Salk and Sabin!!!
