The brain reacts to every thought of ours. All our thoughts are usually thoughts from the past. They are repeated especially if we have to make an important decision. We need to give an installation that everything will be fine, everything is solved and the possibilities themselves will start to appear. Periodically, it is necessary to clean thoughts and try think only on the positive. You can dream of traveling to interesting places, meetings with interesting people. New impressions, active rest is a rest for our immune system. The brain trains when we even sleep and its activity is high. The brain reacts to pain but he does not feel it because of the absence of receptors. Any activity causes the brain to generate new neural connections.
