It has been found that playing sports not only develops muscles but also develops the brain. Finnish scientists conducted a voluntary study of 10 pairs of male twins to determine the effect of sports on the brain. Participants in the experiment performed various sports exercises at different levels, and unexpected and surprising results were obtained. In addition to the development and enlargement of the body muscles of the twins who actively practiced sports, it was seen that the activity of the part of the brain that is responsible for the direction of human movement was activated and its size increased. These scientists concluded that this discovery could be useful in the future for the treatment of diseases related to the part of the brain responsible for body movement orientation. Therefore, the time has come to defeat the diseases that paralyze and numb parts of the body.
