I'm born around that time although before 1981. I had some elderly neighbors with this condition and I think they lived long enough (1990 maybe?) that my two next younger brothers might have visited them too. (Why I don't know: they were not relatives or anything, my mom and aunt just used to visit them to be nice to them, so I suspect when I started school they might have taken my place.)
