"Volleyball is perhaps the best sport ever devised for correcting the "student stoop" since, if the net is kept high and the two-handed return used, it compels players to keep the head and shoulders up and back, the spine straight and the chest thrust out. It is a good game for the spectator, too, since he can sit close to the small court and keep the ball in constant view, and yet it is hard for a spectator to watch it very long without acquiring a strong impulse to pull off his coat and join the players."
