Well, because it reveals mysteries about human beings, such as this:
Men are really interested in women. Actually, this study did have a pretty interesting finding:
After 300 seconds alone in the same room as a woman they had never met before, and in some cases did not find particularly attractive, the men's testosterone levels of the hormone had shot up by an average of around eight percent.
In other words, we guys are more desparate than picky. Also in the story:
The rising levels may then fuel more visible changes in male behaviour that occur in the presence of a woman, including a squaring of shoulders, an upright posture, and greater use of hands - and even, it is suggested, a flaring of the nostrils.
Yes, greater use of hands. So if a guy is getting a little "handsy," he can blame it on human nature. I'm not sure how that would work in court.
