Boas, recentemente aprendi malabarismo, e actualmente consigo fazer-lo com 3 bolas.
Andava entretido a tentar fazer com 4 (2 em cada mão, sem trocas) e reparei que o meu braço esquerdo tem mais dificuldades em fazer certos movimentos. Como experiencia (ou treino) começei a usar o rato do computador na mao esquerda, e achei a experiencia bastante interessante e agradavel.
Escrevo com a mão esquerda desde que me lembro, e durante algum tempo na primaria fui ambidestro.
Quando era pequeno comia com a mão esquerda, mas a minha mãe "corrigiu-me" (ela diz que ainda hoje se sente culpada, mas não sei se eu estava destinado a ser canhoto, ou se foi uma fase).
Com o tempo fui perdendo o jeito com a mão direita, mas o braço dominante sempre foi o direito.
Ou seja escrevo no papel com mão esquerda, mas num quadro com mão direita.
Pesquisei hoje na net sobre ambidestria, e deparei-me com resultados assustadores:
Converting handedness, whether it be from a dominant left hand to a non-dominant right or the reverse, (especially during writing) does not result in a change in cerebral dominance but rather a multifaceted cerebral disturbance or damage. This functional cerebral damage (dysfunction, blockage, and inhibition of brain functioning) can then be manifest in the following primary disorders: disturbances in memory for all three areas of information processing (encoding, storage, and recall); difficulty in concentration (early fatigue); difficulty in reading and spelling (legasthenic problems); spatial disorientation (e.g. confusion of left and right); speech problems ranging from stammering to stuttering; fine motor disturbances evident in writing and other activities requiring precision.

.....Rats given diverse and enriched environments have more connective dendritic spines to their neurons and overall heavier brains than rats exposed to dull, unchallenging environments. Left-handed and ambidextrous people have 11% larger corpus callosa (the bundle of nerve fibers joining the right and left sides of the brain) than right handed people. An autopsy of Einstein's brain revealed a larger profusion of superficial capillaries interlacing the cerebral cortex than the average brain, as well as an additional amount of glial cells. Obviously the more we use and exercise our brain, the more it physically grows. The following exercises are designed to task the little used areas of the brain to allow such growth.

Dr. Karen Rogers, a researcher of international renown, analyzed data at the Gifted Development Center in 1994-1995 during a postdoctoral fellowship. The analysis consisted of data on 241 children between 2½ and 12½ years of age, with IQs ranging from 160 to 237+ on the Stanford-Binet Intelligence Scale (Form L-M). Here are some of the findings from that study:
...
48.9% were ambidextrous at some period of their development.

Vou alterar a minha maneira de pensar, ou fazer danos cerebrais, ou aumentar as minhas capacidades criativas se aprender malabarismo, e tentar "brincar" com a ambidestria?
Alguem ja pensou sobre o assunto? Mesmo que não sejam respostas completas, qualquer opinião é bem vinda
