This solo drill takes about half an hour and involves a zip of water. Fill your mouth to the lower lip level with water and start walking. Breath in through the nose and exhale as best as you can through the mouth. From time to time stop and squat down and look around (Do this drill outside) after you check out your environment from all directions and from different angles continue. When you finish drink or discard what was once just water and enjoy the feeling of your mouth liberated. You will notice patience and a relaxed but aware jaw will serve you better when impact comes along. Check it for yourself and find your way.
