Likely not related, but I was recently researching pitbull behavior and found that nearly all pitbull attacks are by un-neutered male dogs.

I have to wonder if there is a similar phenomenon with high testosterone human males.

In the end, even though humans have higher thought than animals, we are still somewhat left to our nature, especially when we are not taught better.

Too much of a stretch? That's just what I thought of as I was reading your article. Thanks for sharing!
