At this time, the urine volume is several times the usual.

4. If someone wants to fight with you, when he throws a punch at you, people will instinctively back up, but they should actually go forward. A human arm can only exert 100% force when it is rounded. When you punch, you face forward and dodge left and right. Even if it hits you, it will only have half the force and no damage. But if you back up, every punch the opponent will do. All are 100% power.
