Weaklings Have Better Hearing

A study finds that weaker people, like women, tend to have better hearing than stronger male counterparts. The weaker participants perceived threatening sounds quicker than others because they thought the threatening sound was closer than it actually was. Such behavior could be a survival mechanism.

Steroids Lingering Effects

Research found that even years after abstaining from steroid use — and little or no weight training — muscle fiber density and increased number of cell nuclei were comparable to drug-free athletes performing high-intensity strength-training. Additional cell nuclei could help former dopers because more nuclei = more protein synthesis = more muscle.

Need Will Power? Flex Your Muscles

The Journal of Consumer Research reports that flexing any body muscle can enhance one's will power.

In one study, those who tensed their calf muscles were more likely to drink more vinegar.

In another, a much larger percentage of people who clenched their fists were able to look at disturbing images of post-earthquake Haiti.

In another, subjects who tightened their fingers were more likely to choose healthful snacks than non-clenchers.
