Eternal youth

Eternal youth is a concept, or dream, that people have of living forever without growing old, like the characters in stories. We don't have a real, scientific way to make people stay young forever, but we can take care of ourselves to try and stay healthy for as long as possible. That means eating healthy foods, getting enough exercise, and going to the doctor for check-ups. Hopefully, if we all do this, we can all stay healthy and young-looking for longer.
