Pretty much, it is saying that a man that is young in age my be old in hours. A youth isn’t like that cause we usually keep moving, we never stay in one spot for a long time, unless we have to. Then it says that a youth is closer to God than an old man is because his eyes are better. I don’t really think that is true, but I will go with it. I think that if we can all be close to God if we keep our focus on him and no one or nothing else.
