Non-photographic stuff in your camera bag

[480sparky]

So I was cleaning out my camera bag today, and realized I had some things in it that really isn't "photography" stuff. I got a palm-sized stainless steel mirror at a sporting-goods store so I can see my camera monitor when it's in a position I can't readily see. I also carry a 'miners' LED headlamp for setting up in low light. In addition, I pack a clip-on red flashing LED light for when I'm walking bike trails at night, shooting along the roadside, or wherever I need to show my presence in the dark.

I'm sure most everyone has things like batteries, extra memory cards, filters etc., but what non-photography items are in your bag?
