I'm sure all the scientific stuff y'all are talking about is true. I sure couldn't dispute it
I only posted because I was responding to your opinion that most athletes, especially football players are violent. You did say that you hoped you didn't step on anyone's toes, BUT... I was responding to that

I'm not mad though, just responding.
Off topic: I think it is funny that people will say things like, "don't get mad when I say this, BUT...." or "don't take this in the wrong way, BUT....", or "I hope I'm not stepping on anyone's toes, BUT..." and then expect that the people they are addressing will not have a negative reaction and respond. My sister would do that to me all the time and it drove me nuts. She would never understand why I got mad when she told me something mean. She'd come back with, "But, I told you not to get mad!" Oh, well then that makes it ok.
Now back to testosterone.
Sorry about all the smile things, I think they are dumb too, but I'm trying to convey humor, not anger...
