众说纷纭

An old man came to my work place. After talk he told me he was already 80 years old. I admired his health and good mood. He felt gratified on his face.

Being healthy and long life is everyone's dream, but how can we do this? Do exercise or Martial Arts helps for this goal? It's hard to say. That old man rarely do exercise, he thinks his health owe to gene.

But anyway, good living habit and passitive mood should be helpful.
