Well Ben, have you noticed that you're gradually aging? The newest studies confirm that almost everyone and indeed perhaps everyone is aging. If later studies bear this out, we'll keep counting birthdays. The big question that remains is whether this is at least in part affected by humans interacting with one another.
This little buck didn't age much past his first birthday. Glad you did! And hope that you have a splendid birthday. If love helps with the process, you'll live to be as old as Methuselah. There's plenty of love coming your way.
