Golf is no longer a closed area
Golf is a sport where the swing means everything. A synchronised movement of the hands, arms and body, which generates a force at the head of the club which on impact with the ball reaches a great speed (between 70 and 100 km/h) and the ball leaves towards the target. It is not easy. A lot of muscles are needed to make this movement and, in spite of the ball being immobile, the difficulty is the small target of impact.
