The following is a quote from a science exam paper sat by an 11 year old -
"A fossil is an extinct animal. The older it is, the more extinct it gets."
There's a lesson for us all there :-)
Also from the same source (quotes from science exam papers sat by 11 year olds) and completely OT I'm afraid.
"To keep milk from turning sour: Leave it in the cow."
There's a lovely logic to that; can we apply it to the future of Stonehenge?
