The question is, what happens to the paper and pen when you fall?
Seriously speaking, what is the quality of these pens? If they can survive space (so assumed) can they survive sky diving? Or for that matter, Dance Dance Revolution? There are a lot of things to be made a note of in DDR, and it would help to have a pen to write down things when you fall down on your rear and need to tell someone to get you up. ^^ Coming of course, from a personal experience that occurred about 18 months ago...
