So Zeno is most famous for his tortoise paradox. Let us imagine that you are in a race with a tortoise. The tortoise has a ten-yard head start. In the time it takes you to run that ten yards, the tortoise has moved one yard. And then in the time it takes you to make up that distance, the tortoise goes a bit farther, and so on forever. You are faster than the tortoise but you can never catch him; you can only decrease his lead.

I had to tell her she would die, so I told her she was going to heaven. She asked if I would be there, and I said that I would not, not yet. But eventually, she said, and I promised that yes, of course, very soon. And I told her that in the meantime we had great family up there that would take care of her. And she asked me when I would be there, and I told her soon. Twenty-two years ago.
