Dependency.

A number of unexplained power cuts at home has made me all too aware of how dependent we have become on certain things. Not only are we like a fish out of water without electricity but think too how much we rely on motor vehicles and computers.
We do not produce even 1% of our own food. Think how vulnerable this all makes us.
Oh. And I am writing this on a borrowed computer - my new one has died and my spare is dead!
Well at least the car works and we have food!
