Ever watched a fight on TV? Before the bout everyone’s milling around in the ring; there’s hard looks and grins and hangers-on and photographers, and a general air of excitement and anticipation, but everyone’s enjoying the moment. Then the bell clangs. Everyone heads to their corners. They know exactly which corner is theirs.

We may think that bell’s already rung, but it hasn’t. Believe me, you'll know it when it does.
