...then maybe the decisions that males make (which aren't always so great, btw, but don't want to be negative) could be blamed on too much testosterone.....
Men's actions and decisions are blamed on too much testosterone by women all the time (e.g. I can smell the testosterone in the room). And there is some truth to that--for men other than myself, of course.
And as a modern, politically correct male--I believe that men and women are exactly the same (except for maybe physically--there we aren't at all alike, and then there's that difference in our brain structures, oh, and that reminds me--the way we think is different, and, well, that's probably caused not only by our differing brain structures but also by our hormonal differences, and....well, anyway....) But all that aside, men and women are exactly alike! We are all unique, of course, except for men and women...who...err...are absolutely and completely alike. Are we good now, ladies?
