More On Taming the Juggling Balls

I’ve been juggling for about 5 months now and reflecting on my progress. I think I’m doing OK for a geezer. Sena would call me a hot dog although I would still call it ugly juggling by any standard.

What’s striking, at least to me, is the little bit of science I can find on the web about juggling. I hear the term “muscle memory” when it comes to learning juggling. Actually, there’s some truth to that. There are different kinds of memory. For example, most of us know about declarative memory, which about memorizing facts, because we use it to prepare for exams. Those of us who went to medical school remember the agony of taking tests for the basic sciences.

But so-called muscle memory, or the memory for learning new skills like juggling, takes place in the brain. There was a study published in 2009 which found changes in both gray and white matter of subjects before and after learning to juggle (Scholz J, Klein MC, Behrens TE, Johansen-Berg H. Training induces changes in white-matter architecture. Nat Neurosci. 2009;12(11):1370-1371. doi:10.1038/nn.2412).

The study about correlation of the inability to stand on one leg for 10 seconds with higher mortality in older patients, which I relate to the ability to do the under the leg juggling trick, was published last year (Araujo CG, de Souza e Silva CG, Laukkanen JA, et al. Successful 10-second one-legged stance performance predicts survival in middle-aged and older individuals. British Journal of Sports Medicine 2022; 56:975-980.)

I talk a lot about juggling as though I’m a teacher. I’m not a juggling instructor by any means. You can find better juggling teachers on the web. But my approach to talking about juggling in terms of it being a hobby for me is really not different from how I talked about consultation-liaison psychiatry before and after I retired. I’m still a teacher—just evolving in retirement.

However, you can find much better resources for learning how to juggle at the following websites:

Have fun!

I'm a retired consult-liaison psychiatrist. I navigated the path in a phased retirement program through the hospital where I was employed. I was fully retired as of June 30, 2020. This blog chronicles my journey.
