Pity The Male Narcissists

Because they suffer:

Men who are narcissists may be at risk for some health problems, since they could have inherently higher levels of the stress-related hormone cortisol even when they're not under pressure, a study finds.

Cortisol, which is released by the body when it's under duress or going through an intense activity, can have some benefits--lending an energy surge, helping the body burn fat, and boosting memory. But too much cortisol from chronic stress can have deleterious effects, such as higher blood pressure, lower immunity and higher levels of abdominal fat.

..."Narcissistic men may be paying a high price in terms of their physical health, in addition to the psychological cost to their relationships," said co-author Sara Konrath of the University of Michigan in a news release.
