The Romans must have been a really careless set of people.

They were also a very clean people. They went to the baths a lot and lost things into the drains. If you ever get a chance, go to Caerleon. There's the Roman Amphitheatre and the excavated baths and the museum has lots of rings and stones from rings that they found in the old drains.

The thing I found really fascinating was the fact that the Roman soldiers used to contribute to a funeral club to ensure a decent burial when they died/were killed. It's exactly what my grandmother and others of her generation did in Manchester.
