Why do we spend a third of our lives sleeping when the hours of the day don’t seem to be enough for any of us? Some would say it’s because we need to save energy, others that resting our bodies also help with other biological functions.

We found this very interesting and suggest you read the whole article by Carl Zimmer / New York Times, published earlier this year.
