It was Einstein (yes, that Einstein) who said:  "the definition of insanity is doing the same thing over and over again expecting a different result."

Aren't we glad that he uttered this statement just a few minutes before he came up with the Theory of Relativity. Really, where would we have been if he had heeded his own words and stopped what he was doing?

It appears, however,  that along with those folk who are deemed insane due to, I don't know, maybe  genetic imbalances, there is another factor at play. It's stress. 

Apparently, the brain when responding to stress releases chemicals into the blood system that, in addition to wrecking havoc on your organs, causes a mechanism triggering you to repeat an action, repeat an action, repeat an action, repeat an action, without being able to stop, repeat an action.

But there is good news.

The circuitry that goes into overdrive can be reversed. One simply has to eliminate the stress. That's pretty easy to do. Take an extended vacation, for example. Just don't come back.
