If we base our belief systems on the humble assumption that the complexities of the world are ontologically beyond our understanding, then maybe our belief systems will make more sense and end up causing less suffering.
The idea of feeling old is much more the worry of a slightly younger person. When you are getting old, that becomes - psssh - completely secondary to the absolute understanding of how short your life is.
I remind myself that the universe is 15 billion years old, and I'm only 46 years old, so my perspective is sort of limited and fear-based and skewed. So I sort of turn things over to whatever you want to call it - whether it's God, or the universe or the spirit of the universe - and I just sort of turn things over to God and hope that this spirit that has been around for 15 billion years will have a better understanding of how things should be than I do.
