World's oldest mattresses found

The History Blog notes that the world's oldest mattresses have been found in South Africa, dating from c 77 thousand years ago.

I'm afraid they've missed one of the key findings. At about halfway down the archaeologists found the remains of the world's oldest teenager - those remains being a pizza box and a can of cola. When the scientists reached this layer, the teenager himself mumbled "yes, all right - I'll get up in a minute", and went back to sleep.
