Paradoxes

I love thinking about paradoxes. Which came first questions or answers? Or "This sentence is false." Is the answer to this question "No."? Which actually did come first, the chicken or the egg? If I traveled into the past, what would happen when I stared at myself? If you shoot an arrow from point A to point B it never gets there because to get there it has to at first cover half of the distance and then another half distance...but there are an infinite number of half-distances so you never get there. I just love these things!
