In my case, I heard about a man with an IQ of 350+, but for some reason he left the country in an unknown direction with his wife and children. Lived like an ordinary person, did not stand out in any way, worked at an ordinary job, I don’t remember which one, but definitely not a teacher, It was a manual profession.
I’ve met quite a few. The most intelligent well rounded people didn’t stand out at all. The ones that stood out the most were those that excelled in specific areas and pretended to be great at everything else too and ironically made them look less intelligent that what they really were.
