More than 1,000 retired workers, all aged 75 or above, stood in line. They were about to sit down to a barrage of tests judging their memory and thinking skills. The tests were grueling, and it was only the beginning. For eight years, these retirees would line up every 18 months for the same battery of tests and evaluations, almost as if they were migratory birds following their instincts.
But they weren’t compelled to subject themselves to the draining tasks and judgments. No, they volunteered — and for good reason.
The brains of these older men and women held the answer to a question neuroscience researchers believed they could unlock: Does a life of stressful and demanding work actually make you mentally healthy?
After eight years of tireless study, sifting through mountains of data, and controlling for every possible variable, they had their answer:
Your life of constant stressors that require fast thinking, prioritizing, and decision making — the things you complain leave you exhausted every day after work — are actually making your brain stronger and preparing it for top performance for years to come.
Why Difficult Work Makes You Stronger
When you go to the gym, your muscles get bigger and your body grows stronger. Everyone knows this, and the path to creating physical health is well-established (even if we struggle to follow it). If you do it regularly, you can expect to enjoy a capable body as you grow old.
It makes sense, intuitively, that the same would be true of your mind. Exercise it regularly and it ought to also grow stronger, sharper.
While the analogy rings true, most health advice you read today suggests the opposite. Don’t overdo it at work. Lower your stress. Regularly take your mind off the hard things. It’s good advice — too much stress is terrible for you, but it doesn’t tell the whole story.
What the eight-year study by neuroscientists at the University of Leipzig found is that forcing your brain to work on difficult problems and juggle a variety of tasks — when done with care — really is akin to lifting weights with your brain. [1]
The thousands of men and women they studied were given the same mental agility tests year after year and, without a bias for race, ethnicity, socioeconomic status, and a myriad of other potential confounding variables, those who spent their days exercising their brains performed measurably better.
We know hard work leads to accomplishment. Now we know it leads to a healthier mind with more longevity, too.
The question is, what can you do to maximize the benefits of your difficult work?
How To Strengthen Your Mind Every Day
If it isn’t obvious by now, the answer to maxing out your brain’s performance abilities for the rest of your life lies in how you exercise it — just like your body. That means building a brain-exercise routine will probably be successful if it mirrors the most successful ways to create any other routine.
In the beginning, that means creating a schedule you stick to until you’ve formed a habit. Then, working to merge it into every aspect of your daily life. Here are a few ways you could maximize the exercise your brain is getting in the different areas of your life.
