The document discusses aging and growing old. It notes that some people experience dementia and revert to child-like behaviors in old age. It also discusses society's fear of aging and attempts to retain youthfulness. However, the Bible says growing old is a blessing. The document analyzes Psalm 71, in which an aging man expresses concerns about declining health and strength but maintains confidence in God. He expects to continue praising God and declaring God's righteousness even in old age. The document advises that the old can secure their hearts by staying faithful to God, maintaining relationships, focusing on blessings rather than complaints, and continuing to serve others.
