The next time you think your brain hurts from studying, don’t worry about it. It turns out that the longer you are a manager, the larger your hippocampus becomes and the better it works. (The hippocampus is the area of the brain responsible for learning and memory, so that’s a good thing.)
Researchers led by Michael Valenzuela of the University of New South Wales School of Psychiatry’s Regenerative Neuroscience Group found that managing other people protects your memory and ability to learn well into old age. They found that the hippocampus shrunk much less in the brains of people who had challenging management careers. They speculated that the unique mental demands of managing people require continuous problem solving, short-term memory and a lot of emotional intelligence.
The brain-enhancing effect of managing others was particularly strong in people who supervised more than 10 people.
So if you want a healthy brain and to ward off neurodegenerative diseases such as Alzheimers, keep studying to become a great manager.
