One of my professors told us he changes the computer mouse to left side or right side every once in a while because making the brain work like that is supposed to prevent dementia later in life.

So, I’m trying to use the mouse with my left hand. Not because of the dementia thing, just as an experiment.

This is very difficult! The muscles on my left arm are already getting tense and the pointer is all over the place. But I’m not giving up.
