a) Spending time calculating a value with way more significant figures than akcually required, b) Calculating
something that shouldn't be calculated, e.g. time "wasted" whilst you're reprimanded by
parents for your trivial
wrong-doings when you ought to have that time to catch up latest YouTube videos
I
spent an hour over-calculating how much time I'd
lose getting yelled at for missing curfew, when I could've just been watching my
favorite YouTube videos instead!
