It's worse than I thought over there. Sad, very sad. I wonder if this is a direct result of the massive loss of life from the two world wars. Maybe the manly gene was nearly wiped out.
All kidding aside, but I've heard that before. That the two WW had a kind of dis-eugenic effect, killing off not only the hyper/barbaric aggressive but the "regular"* aggressive type leaving the bulk of the survivors the moderate, the cautious, and the timid.
