Good God no, I'd be fucked!
Number of things entertained? Per second? Me? Fuck!!
Thing is, I don't even think they're true...
Actually that should be another thing to put into it then - not just number of things entertained that are probably true vs number of things entertained, but also number of things subject believes to be true should enter the equation somewhere.
Cos like I say, I entertain shit all the time, some true, some total crap, some debatable. I have to say I've a pretty realistic estimation though of which is which. I mean geez, just cos someone's got an imagination, that doesn't mean they're deluded! Some people just like to play with ideas
