Random thought during lecture

I was taking notes with my right hand and realised that I was taking notes with my right hand.

I wonder whether the human brain is more.... shall i say used with more balance now that people type more and write less.
Hence the use of two hands is more than simply focusing on your writing hand.

So in a way, our non-writing hand is being trained more. With the combination of lessons of history and how our culture has evolved, is that why we have a more holistic approaches to everything now that our brain is more balancedly used?

Psychologist are going to grill me for this passage lol.
