How can I regain my youthful disposition? How can you stay young?

A positive disposition plays a big part in feeling and looking young. If you get stressed over petty things, that is not going to help. As much as possible try to get rid of negative things in your life and strive to take things lightly, although this is easier said than done. Smile a lot. It's the fountain of youth, the all say. A healthy diet, of course, is essential to keeping your body strong. Eat less carbs, moderate protein, and more fruits and vegetables. Lastly, think young and you will feel young.
