i'll let you guys in on secret: women love men who treat them like dirt :S because as soon as that man shows he cares in some tiny way at all, it makes them feel special.
what a world.
also, i would assume the brain shrinks due to the woman's body having to work so hard to keep and maintain another living organism within it...but i suck at sciency stuff....ohmagawd he said 'sciency...' whatta retard!
