Lost that is true

My son used to play junior rugby and in that, girls were allowed to play as long as they had not reached puberty.
Any match between young boys & girls - the girls would win. They take direction (follow instructions and dont go off doing their own thing at the expense of team play).
They possess a savagery and determination that young boys do not possess. And yes, a deviousness, young boys are no match.
Of course they tend to lose this when puberty kicks in and hormones start to flow
