This is the view the Bible holds on age. In the story of Job, we find that Elihu the younger of Job's friends waited until the older men had spoken to Job. He also treated his communication to Job with admiration and respect, since Job was his elder. He goes on to say that the Pharisees had made void the law of God by their disgraceful treatment of the elderly. I am reminded of Caleb, who at the age of 85 came to Joshua and took possession of that inheritance he had earned.
Age demands an inheritance.
Old age should be a time for ego integrity. The elderly have made their mark on life. They have performed well, and have confidence that their life was well spent in raising children, making the world a better place, and in training the next generation. They have a wealth of wisdom to share, experience to relate, expressions and advice on life to share. They await new experiences, and are getting prepared for the last experience of this life, and for a whole new world beyond death.
