Every politician I have ever seen has been physically pathetic. Right and left wing. I always figured that's why they got into politics, because they were never going to experience what it was like to be physically big & strong.
And it's junk science studies like this that has given academia a bad name. No longer is research based on truth, but some retards bias that they don't even try hard to hide any-more.\
And equating bicep size with the ability to win in a physical conflict - really? This is what happens when you have a bunch of physically weak academics trying to determine what physical strength is and who has the greater benefit in a conflict.
