To learn something, we need the right hemisphere more, but when we reach a certain level of proficiency, those activities become controlled by the left hemisphere.
For example, when you learn to drive, you need all your senses and it seems to you that you will never be able to do everything at once: the clutch, the gear control, the forced stop at a stop and, above all, the teacher who asks you questions … Without Over time, however, you can not only drive around town without stress but you can also listen to music, talk to the person next to you, and can even talk on the phone (with a hands-free phone, of course!) without you miss a red light.
Why is this happening? Because he has reached such a level of learning, as far as driving is concerned, that his left hemisphere has this learning automated . And that is fantastic because it is what allows us to do several things at the same time without stressing ourselves and without having to think about each step that we are going to take BUT, this automation of most of our daily acts, although it makes life easier, represents also the death of many of our neurons since they are not requested.
Routine is the worst enemy of our neurons but there is a simple remedy: train them. In the same way that we go to the gym to stretch the muscles of our body, we can train our neurons with a simple “brain gymnastics”.
