There are many people who prefer to use one side of the body for certain activities, and the other side of the body for other tasks. Also known as cross-dominance, mixed dominance, or mixed handedness, it is often confused with ambidexterity, in which a person can use either side of the body equally well, with no preference for one side over the other, for activities like writing or throwing a ball.

As a cross-dominant individual, I write, paint, draw, and perform medical procedures with my left hand, but throw a ball and hold a racket with my right hand. Consequently, the right side of my body favors gross motor tasks, while my left side dominates when it comes to fine motor skills.

One of the best ways to protect brain function is to engage in activities which are mentally challenging, yet enjoyable. The trick is to pick an activity which promotes learning or skill, without aggravating or frustrating you.

Before you assume that you’re too old to make positive changes in your brain power, keep in mind that scientists have determined that older brains are still receptive to boosts in cognitive function.
