Under normal circumstances, running will make people walk lightly and full of energy, which is obviously better than people who don't insist on running or don't exercise much.

However, running is often an outdoor sport. It takes three or nine days in winter and three days in summer. The skin will be slightly rough and dark under the wind and sun. When you are young, you will look older and bigger than your peers, but this state will last for a long time. When peers begin to feel overwhelmed, people who insist on running seem to have no obvious physical aging characteristics. The older you get, the less you look old.

Of course, besides running, it is also related to other living habits, but in general, running will make people healthy and agile, which is really obvious.
