The journey of life is like a man riding a bicycle. We know he got on the bicycle and started to move. We know that at some point he will stop and get off. We know that if he stops moving and does not get off ... he will fall off.

The bicycle is a former child's toy that has now been elevated to icon status because, presumably, it can move the human from pillar to post without damage to the environment.
