Why weren't women included in this 'study' by psychologists in Knox College in Galesburg, IL? It seems 30 men were "blinded" to giving saliva samples after either disassembling a gun or a game of Mouse Trap. The headline: "In Men, 'Trigger-Happy' May Be a Hormonal Impulse" appeared in the New York Times. I bet a women's epinephrine level (and maybe even testosterone level) would have climbing just as much disassembling a gun versus a game of Mouse Trap. Pity these sexist studies persist. Pity worse the NT Times for publishing this blather.
