Going out to dinner, watching a movie, or a taking a walk in a new part of town are fun things to do. Some people might think these activities are a waste of time. But think again!
Researchers say doing things that are fun boosts your brain power.
The brain is like a high-powered computer. For example, you type information into a computer,
which sorts the information. Like a computer, your brain needs information, too.
Everything you
see, hear, smell, touch, or taste gives your brain information.
When the brain sorts information, it tries to link it to what you already know or have
experienced. If you have the same experience more than once, the brain forms a pattern. The
more you do something, the stronger the pattern becomes. For instance, you might take the
same route home from school every day. The pattern is so strong that you almost don't have to
even think about where to go. Your hands and feet move automatically when you drive home.
The brain isn't getting any new information. That's why researchers say it's good to take
different routes.
A new experience also gives your brain a chance to make new links. More links mean more
brain power. A fun trip to a new place is not just a good time. It's also a way to get smarter.
