Juggling may increase size of your brain

Waddaya know, all my juggling practice may pay off in increased brain size. However, if this equals increased intelligence is another question. I'm pretty fluent juggling with two and three balls, and can perform several tricks. If this German study is correct, I should start practicing again...

The scans found that learning to juggle increased by about 3 per cent the volume of "grey matter" in the mid-temporal area and left posterior intra-parietal sulcus, which are parts of the left hemisphere of the brain that process data from visual motion.
