If the whole of the Earth's history was a single day, then human beings would not have arrived home until 6.15pm, halfway through the Simpsons on BBC2.

Humans would curse their miserable luck, before realising that it was only a repeat anyway, and that maybe they would enjoy an evening of different television delights instead, pondering whether the presenters of Food and Drink could get any fatter.

Remember: The human race isn't a sprint. (it isn't a marathon either, because a marathon is 26 miles, and if a human being stopped functioning after covering 26 miles, then they wouldn't live very long)

The human race is a steeplechase. Anyone can see that. Logical brains are good, but don't get cocky. There are some tough jumps ahead.
