The second theory is similar and is known as "evolutionary neuroandrogenic (ENA) theory of male aggression".   Testosterone and other androgens have evolved to masculinize a brain in order to be competitive even to the point of risking harm to the person and others. By doing so, individuals with masculinized brains as a result of pre-natal and adult life testosterone and androgens enhance their resource acquiring abilities in order to survive, attract and copulate with mates as much as possible.  The masculinization of the brain is not just mediated by testosterone levels at the adult stage, but also testosterone exposure in the womb as a fetus. Higher pre-natal testosterone indicated by a low digit ratio as well as adult testosterone levels increased risk of fouls or aggression among male players in a soccer game.  Studies have also found higher pre-natal testosterone or lower digit ratio to be correlated with higher aggression in males.     
Hardy made his first wrestling appearance after being released from WWE at an OMEGA show, on May 24. Using his old gimmick, "Willow the Wisp", Hardy challenged Krazy K for the OMEGA Cruiserweight Championship, but lost the match. Hardy performed with the Ring of Honor (ROH) promotion on one occasion. Hardy appeared at ROH's 2003 show, Death before Dishonor under his "Willow the Wisp" gimmick, wearing a mask and trench coat. Hardy was quickly unmasked and lost his jacket, wearing attire similar to that he wore in WWE. Hardy was booed and heckled before, during, and after the match by the ROH audience, who chanted "We want Matt!" and "You were fired!" during his match with Joey Matthews and Krazy K, which Hardy won. Hardy then took a whole year off of wrestling to concentrate on motocross and finish his motocross track.
