As the trucking world twirls, more and more of us are working longer and longer hours.

There is more work to do because there are fewer people to do it as companies downsize.

As my brother Steve is fond of preaching: “It is what it is, and you need to do what you need to do.” True enough but, putting in too many long hours could be affecting our brains.

A recent study found that compared with working the typical 40-hour week, middle-aged workers who put in more than 55 hours per week had significantly lower performance on a series of mental skills, reasoning, and vocabulary tests.

More disturbing, the research adds to the increasing evidence that establishes a link between cognitive impairment and later life dementia.

The study stated that the “cognitive functioning between employees working long hours and those working normal hours is similar in magnitude to that of smoking, a risk factor for dementia.”
