Actually, don't tell anyone, I was an Engineering major, before I switched to math, then thought hmmm physics....and then went on to take more psychology courses than anyone should have if they are not a psychology major.....nd then somehow end up in IT.... but as a professor I once had said, knowledge is not so much what you know, but knowing where to fin the answer.
But for the record, to avoid upsetting others, I am not serious when it comes to this metric discussion.
Besides, its "proper American" and "meters"
As one who has a degree in psychology and wound up in IT, I understood and could apply DSM to the specimens of upright apes that hooted through the corporate environment.
I mean, who can avoid the obvious political implications of Folie à deux - Wikipedia in the current environment.
