I think once you tip on day past 40 you start to think about life and death. I've been asked time and time again "If you don't marry or have children, who will take care of you when you are old?" My answer is always "Me."

I don't ever want to be a burden on someone when I'm older. I want to live a full active life until I leave the planet and quietly slip away to whatever is next.

Still, like I say, I want a full, satisfied life.
