When you read too much of the big stuff, like all that hyperoxyhexagonal1-23-triathlon-oxybutyl-methyl yadyadyadyada, you forget the little stuff you learnt in grade three.
Don't say I didn't warn you when your daughter who's in grade three asks you a question from her science book, and you, a dad who is called Dr. by academics(as opposed to medicine) can't answer, and you call out to your wife for assistance(assuming she hasn't also gotten done in by the big stuff).
