A Princeton researcher, Les Fehme (Brain/Mind Bulletin vol. 8, no. 9. May 1983), suggests that we can optimize our overall performance in life by broadening our attention. Juggling is a great way to do this. He states that most people have narrow concentration, a lack of awareness of their bodily sensations or emotions. This narrow focus can be very engaging and helpful, such as when talking on the phone, riding a motorcycle, or receiving a massage. It's like nothing else exists except that. When learning to juggle, the narrow focus may be directed at a certain ball or pin. This narrow focus accords with the observation that we live in a society that sees things as fragments rather than holistic. But things are changing. And perhaps, juggling is helping to change that. In 1983 a Canadian researcher, Justine Sergent, of McGill University in Montreal, found evidence that challenges the idea that the left brain is analytical and the right brain holistic. Instead, his findings show that the left hemisphere is better at detailed processing (the narrow focus) and the right hemisphere better at broader aspects of perception. These findings also found that both hemispheres of the brain were analytical and holistic. The study also suggests that because as a society we "see" life and things as fragments (a ball or pin instead of a pattern), this could explain why there are more right-handed people. A recent "surprising" discovery according to a researcher, Brenda Spiegler of Children's Hospi...
