Time goes on and never stops. Without us knowing our age has grown older. There are some things that indicate that our age is getting older: our body resistance has begun to decline, our energy has begun to decrease, hair has begun to whiten, eyes have started shortsight, teeth start less healthy, the skin has begun to loosen, and can not eat good food again. old age does come without us knowing it, but if we look will show the symptoms on our body.
