My wife and I are a team. We both recognise there are differences which we applaud and similarities which we also applaud. Combined we are more formidable than any single person so it's a partnership that really works for us both.
She outguns me for business, marketing ad heaps of business skills and more. I outgun her in practical skills, IT knowledge, navigation. etc etc.
Works for us. Differnt brains working diffeent ways.
I don't really beleive IQ is the real measure of abilty, it is only one perspective. I know many people who would score poorly on an IQ yet they can still excell and beat me at certain skilled tasks. It's as much about aptitude and attitude I reckon.
Each to their own I guess and viva la partnerships !!
