Over the years I've observed how someone's physical state affects their psychological/emotional state. When someone's mobility is compromised due to illness/injury and they become bed bound, pretty quickly their cognitive function seems to decline from my observation. It does make sense from a neuroscience perspective because of all activities that take place in the brain when planning and executing motor actions. I also noticed that people who have very sharp cognition tend to be physically active. It makes sense why we can usually have better focus after exercising. As Moshe Feldenkrais said, "Movement is life; without movement life is unthinkable." Let's get moving!
