A Face Lost In A Crowd (Or A Plastic Head Lost In Your Colon)

This week, two very different stories about lost (and found) things:

• Remember the sinister company that scrapes all of the faces from Facebook and sells that information to the police? Well, the police have been using it a lot.

• Some months ago several heroic doctors swallowed plastic Lego heads to see how long it would take them to work through their digestive systems. This is their story.
