And to think people on this very forum were claming the millenium bug was really a big scare and nothing happened
I'm guessing it's not even that the applications/software behind this is that old, just someone forgot (or wasn't around for) the lessons of the y2k issues
I mean this is going to be an outlying case, in that there won't be many 100+ year old people doing it, but it does show that someone (or probably several people) didn't think that programming the app to recognise more than 100 years difference between DOB and current date was worth the extra two digits.
