Is it short-lived to walk without touching your heels?

It is not credible to say that not touching the heel has nothing to do with short life span. The heel does not touch the ground, which is mainly related to your incorrect walking posture. The correct walking posture should be to stand up straight, the abdomen should be straight, the eyes should look straight ahead, the arms should be relaxed at the sides of the body and swing naturally, the toes should be slightly extended outward or forward, the stride should be even, and the distance between the feet should be about one foot to one and a half feet, which can be corrected through logistics and practice.
