I work with a woman (29 and a mother of one) whose lack of general knowledge I can't quite believe to be normal. Ask anything about TOWIE or IACGMOOH and she knows it (unlike me) but the following are just some of the things she hasn't known in the past couple of weeks:
- that we aren't "doing cows a favour" by milking them
- that tea grows on bushes (or that it's a leaf)
- that coffee comes from beans
- that bees are being threatened by modern farming practices and that if there are no bees we will have no plants (inc fruit and veg)
- that reindeer are real
- that early humans lived in caves
- that a month isn't 4 weeks
She "has no idea" how anyone can know this stuff. 
Is this normal now? My 6 year old knows most of this!
