More and more NFL players have been willing their bodies to science so that their brains can be studied even if they die of other causes.

The families of many athletes - incensed at the sports leagues and hoping to make games safer overall - are increasingly making the brains of players who die prematurely and suspiciously available for study. Some athletes are even making the bequest themselves.

As the National Football League and other pro sports increasingly reckon with the early dementia, mental health issues, suicides and even criminal behavior of former players, the risk of what's known as chronic traumatic encephalopathy (CTE), is becoming clear.

Since narcissism is fueled by a greater need to be admired than to be liked, psychologists might use that fact as a therapeutic lever - stressing to patients that being known as a narcissist will actually cause them to lose the respect and social status they crave.

When an organization starts hemorrhaging talent, CEOs and boards of directors want to know why. If the boss gets blamed for the brain drain and is ultimately removed, it means relief for the employees still there and ex post facto vengeance for the former ones.

The most decisive and certainly most delicious option for an aggrieved worker in a narcissist__ office is simply quitting. Slamming your resignation letter on the boss__ desk and striding out to take a better job somewhere else is satisfying and in both its finality and its totality. Instantly the feared figure is stripped of all power, reduced to a person of utter inconsequence in your life. Not only does this spell immediate freedom for the exiting employee, it can also contribute to the long-term decline of the boss.
