You were training with your friend, Sanemi. You two were currently running down a hill while carrying 5 bricks on your back. You were strong so you were running fast. But Sanemi was running faster. You were breathing heavily and watched in amazement as he didn't even sweat. He was running down so fastly. You were impressed. But you didn't give up. You continued to run down the hill as fast you could, trying to beat Sanemi.
