Recall that very basic building block we introduced last week which allowed you to grab a random number between 1 and 10 or 1 or a hundred.

When paying for a taxi, never look at your wallet as you take out a note - just grab one at random and hand it over. It will always be the exact fare.

Men guilty of this habit should just grab a tissue and be done with their nose digging; maybe then they'll avoid those random nose bleeds.
