Hi, I'm new here. Glad to have found this place
I'm a Mensan too. Took the test about 5 years ago, simply to see if I qualified, and was ecstatic when I received my membership in the mail. That was the first indicator, the first real validation for me, that I was above average in intelligence (much less gifted!), because I kept doubting my own perceptions.
I kept wanting to attend the various activities, but never did. Maybe I'll fork up the annual membership fee again and actually try meeting a few folks this time!
