I completely agree with your message, in this sport there are no minuses, moreover, my brother had eye surgery and the doctors recommended him to be engaged in table tennis. This is a sport useful for short-sighted, farsighted, and those who have recently performed eye surgery. The eyes during the game continuously do exercises, focusing on the flying ball, then flying right at you. It is also good for those who work at the computer and watches the screen at the same distance all day. Thank you for the interesting story.
