I'll be honest: At first I thought that this posting on Heavy Boots was total nonsense, one of those urban legends.
But for a lark I tried the quiz on a very smart person I happen to know, one who didn't have much of a science background. And — spookily — it was right on script, down to the heavy boots.
So there is something to it.
The mind boggles. (How long before all the boggle is used up, I start to wonder.)
