(Please say no).
I am currently catching up on paperwork and phone calls relating to my study of children's language that has been going on for about 4 years now - I won't be able to call people at a reasonable hour nor post things to them while I'm overseas. One thing I've been doing is asking parents their dates of birth. Lots of the parents are older than me (but the kids in the study are rising-five). But I am obsessively working out how many of them were older than I am now, when their babies were born.
I am, at the very least, a sad individual. Sorry.
