I have suspected it all along....
Alex is the wife and I am the husband. We are the opposite.
We took a test and it confirmed my suspicions. Alex found this test somewhere on line during work (though he constantly complains about having so much work to do he manages to find time for self assessment tests). It tests quite a bit of things which are designed to determine right or left brain hemisphere dominance.
Alex's score fell JUST short of the average woman's score and my score fell JUST short of the average man's score. I am systematic, a linear thinker, logical and not at all very empathetic like the average woman.
I have taken/been through other assessments of this kind which all point in this same direction...I like process, logic, rules, data, strategy...etc.
But I think this is exactly why Alex and I are married...together we make the perfect, balanced person.
