Tall: You should be commended on your interest of attaining a healthy lifestyle. Assuming you are getting enough calories for adequate growth, genetics plays a major role in determining how tall you may be. Thus, you won't be able to make yourself grow taller. However, you might not be done growing. A simple answer to making yourself look taller is to stand up straight and walk with confidence.
