It sounds like a cliché, but the best is yet to come. The far side of 50 is a good place to be. Despite the losses, aging is not about losing.
Sin's curse results in physical deterioration and eventually death (Genesis 3:16-19). Aging is the accumulation of undergoing physical, emotional, social, and psychological changes throughout life. These changes can bring about loneliness, lack of purpose, guilt, self-pity, loss of friends, and limiting health issues. They become more problematic as we age.
Who hasn't felt him or herself standing on tiptoe, straining to see what lies ahead? Every generation has had its share of individuals who believed they had the supernatural gift of foretelling the future.
Aging is the one thing we can't do anything about. If we're alive, we're aging. The alternative to aging is not the most exciting activity.
