Absurdly Driven looks at the world of business with a skeptical eye and a firmly rooted tongue in cheek. 

You know you work too hard, don't you? 

Because you're an American and that's what you're supposed to do in order to be admired.

Have you ever thought, though, how much it's affecting your mind? Or the minds of your fellow Americans?

I've just accidentally meandered into a study that might begin to answer that question.

Performed at the University of Melbourne in Australia, the study sought to wonder whether too many hours of work might cause cognitive functions to deteriorate.

Specifically, the researchers were fascinated as to the effects of too much work on those aged 40 or more.

I've just crept into this demographic (humor), so I was especially moved by what the results could be.

The researchers examined 3,000 men and 3,500 women. They gave them three different tests of cognitive ability. 

I'll let them declare their own conclusions, while I book a trip to the beach: 

For working hours up to around 25 hours a week, an increase in working hours has a positive impact on cognitive functioning. However, when working hours exceed 25 hours per week, an increase in working hours has a negative impact on cogniti?on.

There you have it, all you over 40's.

Work is killing your brain. I suppose that's why they call so much work mindless. Because that's what you'll become if you keep doing it. 

The researchers also indicated that there was no significant difference between men and women.

They also concluded that These researchers concluded that those who worked more than 55 hours a week had cognitive skills worse than either the retired or the unemployed.

All our brains really are done in by this constant labor. 

In essence, then, full-time work should stop at 40. Everyone over 40 should have a three-day work week.

Unless, that is, we want to make ourselves dull-witted before our time.

Which might leave at least some people wanting to offer a message to Elon Musk. 

The Tesla CEO seems to believe that you'll never achieve much unless you work at least 80 hours a week.

Elon, you're 47. Slow down. All this work is wearing your mind out. 

And you'll need it when you get to Mars.
