Men are usually more interested in a women's breast size than her I.Q. I usually find. That is a much more noticable thing than the aforementioned test score. You can actually get a T-shirt for women which says "My face is up here", across a woman's chest.
IQ is only a measure of intelligence, it is what you do with it that is important. For instance, my son has an IQ of 160 which is genius level, I believe, but he has never done anything with it at all. He would rather sit and read than do anything else. As for pushing back the boundaries of science, forget it.
short of dementia related issues, your IQ remains constant over life, apparently. However, one thing they are picking up on is the type of profile can differ. My ex and I had similar IQs (over 150) and we are very differently profiled especially on maths and verbal reasoning......the frightening one is my youngest who, age 8, is way over 180.
DT I hope your son doesn't waste it, that is a really high IQ. He could be the one to save the world in the future. How exciting that would be. He must certainly be gifted.
