Go ahead. Indulge your fantasy. Would you want the stone tablet to say people should die of old age, or that people should live as long as they wanted? If you could write the stone tablet yourself, what would it say?

I'm reminded of one of Bill Watterson's Calvin and Hobbes strips:

Calvin: I'm at peace with the world. I'm completely serene.
Hobbes: Why is that?
Calvin: I've discovered my purpose in life. I know why I was put here and why everything exists.
Hobbes: Oh really?
Calvin: Yes. I am here so everyone can do what I want.
Hobbes: (rolling eyes) It's nice to have that cleared up.
Calvin: Once everybody accepts it, they'll be serene too!
