For a long time, the scientific community believed we were born with a certain number of brain cells and neural pathways and that, once damaged, they could not be repaired. In reality, our brains are much more flexible. Depending on our lifestyle, we can weaken or destroy connections, or create new, stronger ones. Engaging regularly in certain behaviors and activities, like physical exercise, addressing mental health issues, meditation, and learning a new language or musical instrument, support new wiring and can make existing pathways stronger. Essentially, we can slow down or somewhat prevent cognitive decline by doing challenging mental exercises to keep our brains fit for optimal power
