I'm not dependent of my IQ. Its only 130ish and as long as I have common sense then I'm fine with it.
I know a boy with an IQ higher than 160 back in the beginning of senior high (if I'm not wrong around 180 now; he graduated a year ago) but didn't join Mensa because of the monotony and superiority. He actually wishes to not have a high IQ percentile because of the discrimination and attention it brings.
