Hi @entity01, the brain is an organ which needs to be taken care of all the time because when a brain stops working the human body is considered dead or inactive. The phrase train your brain specifically talks about having our brains in the right frame of mind, avoiding anxiety, depression, stress and trauma. We can have a healthy brain if we engage in recreational activities like playing chess, ludo even football. Without making use of our brains to think we cannot perform our various life activities, this will then result to low standard of living because of the inadequate use of our brain causing societal issues. We can take care of the brain by abstaining from alcohol and consuming food which can help boost the brain function such as vegetables, protein and fatty acid. Well done amigo, you have written an article with facts concerning the topic "train your brain".

Sincerely @chiagoziee.
