Boys work harder for caffeine than girls do

This study showed that boys will play a computer game longer and harder to get a caffeinated drink than girls will. The authors are surprised. They expected heavier consumers of caffeine to play harder than lower consumers, but instead found a boy-girl difference. They speculate it might be due to circulating hormones at the time of the test, or maybe girls are less sensitive to caffeine. I think boys like to play computer games more than girls do.
