The activity in different parts of their brains also became more synchronised. Their low-gamma waves, in particular, became twice as synchronised when they were in their near-death state than when they were anaesthetised or awake. These features have been linked to conscious perception in earlier studies.
Tug of war is a sport that directly puts two teams against each other in a test of strength: teams pull on opposite ends of a rope, with the goal being to bring the rope a certain distance in one direction against the force of the opposing team's pull.
Brief group on normal tug-of-war safety rules, basically: no wrapping or tying rope around anyone or anything - only hold rope with hands. watch out for rope burn on hands - let go if rope is moving through hands. watch out for rope burn on body - let go if you lose footing.
