According to this study by some researchers at the University of Regensburg in Germany, juggling can actually make your brain get bigger. In their study they took brain scans of 24 people who didn’t know how to juggle. They then taught 12 of the volunteers how to juggle and had them practice for 3 months. At the end of this period they took brain scans of all the volunteers and found that the juggling group actually had larger brains!
So, if you want a bigger brain, learn to juggle or joggle. You can learn how by checking out one of the juggling resources on the right side of this blog.
Incidentally, the effect lasts only as long as you practice. If you stop juggling, your brain shrinks up again.
