Interesting read man!
I would agree that the optimal fighter would come from authoritative parents based on the capacity to take the correct decisions at the right time when confronted with a problem.
BUT!
I think the top fighters we see today (at least in MMA) are those from broken homes that had nothing else and poured their hearts and souls into the sport and are the best.
They are probably not efficient though. The amount of blood, sweat and tears and shear amount of time spent training must be through the roof. Often the elite fighters have no life outside of the gym. Eat, train, sleep!
I bet the ratio of training/results would have been much better had they had authoritative parents.
Once again, kick ass article. You should have added a "bjj" tag m8!
