Some over-the-hill birthday sayings employ a comedic approach, lobbing good-natured, age-related zingers at the birthday guest. The humor is often based on the aging human body, the deterioration that comes with getting older and the simple passage of time. For example, classic comedienne Phyllis Diller knows she's old because, "My back goes out more than I do," and Bob Hope quipped that, at senior citizen birthday celebrations, "The candles cost more than the cake."
Other over-the-hill birthday sayings operate from a more sincere, optimistic and uplifting perspective. They provide encouraging words and messages of hope, such as the argument that you're not over the hill at all; instead, "You're at the peak." Or Betty Friedan's viewpoint that aging isn't about "lost youth," instead it's a "New stage of opportunity and strength."
Some birthday sayings emphasize the other side of being over the hill, as opposed to the milestone itself. Such as Shakespeare's belief about mid-life that, "The golden age is before us, not behind us," or Arthur Schopenhauer's caution that once you are over the hill, "You begin to pick up speed."
Over-the-hill birthday sayings sometimes adopt a poetic or philosophical approach. For example, Mark Twain believed aging was a case of mind-over-matter, advising, "If you don't mind, it doesn't matter." Jules Renard knew it's less about how old you are and more about, "How you are old," and Dylan Thomas famously encouraged readers to resist the darkness of old age and, "Rage against the dying of the light."
