How old is goldilocks?

Goldilocks has another meaning, apart from the moral story of the juvenile house breaker who steals porridge at her peril.

In the scientific sense, it is the conditions of Earth. Not too hot, not too cold, but just right (just like the porridge that Goldilocks stole from baby bear.). Earth orbits the sun in this "Goldilocks Zone" giving the right conditions for life to form and thrive. If the Earth was any closer, it would be too hot; any further away and it would be too cold.

The fact that Goldilocks isn't killed by the bears is a testament to the avoidance of unnecessary deadly force.
