Lots of people have questioned my sanity. My wifr works as a social worker in a psychiatric hospital, Once, one of her gay co-workers (there were a number of them, this one was OK), told her. “Chesley is right on the edge”. Can’t say that he was wrong, although he was already over it, as were IMO, many of the workers there.
Now, my IQ. I’m not going to ever knock Einstein off his pedastal, but I earned a PhD in engineering, so I’m fairly satisfied with it. The bet was rather stupid, though.
Well, no, actually, all that still depends on how much you won.
You may be quite sane, have gobs of IQ...but then there's the common sense factor.
