Well. Shuckydarn,
At 14, my IQ was 147 (whatever THAT meant!) and I’m sure it’s much higher now. Still, I’m not an engineer, I haven’t been able to explain a daggone thing to anyone, and I most likely can’t ‘splain anything more complicated than a GI can opener to anyone. It’s for sure the zipper is beyond me...
And my personal life is not even worth discussing.
Being an engineer has little to do with 'splainin' things -- it's sometimes much work for engineers to explain things to other engineers (we're engineers, not teachers). Being an engineer comprises three things: knowledge of How Things Work, education in Applying Same, and (sometimes) vision of Application Where It's Not Yet Been Tried. You clearly have the first in spades and at the very least a very good handle on the second.
I know little about CFIDS, but without it I bet you could still become an engineer. You just have to dumb down to our level. *\;^)
