For me, as a nerdy geek type who programs all day long under fluorescent lighting, it's fun. I like having with me something someone needs. I like being prepared.

On the serious side, I don't want to be part of the panicked multitude if/when an emergency occurs. I want to know enough and be prepared enough to get home. Or to hold out until help arrives.

On the lighter side, I want to live long enough to be a burden to my younger sister. <img src="/images/graemlins/grin.gif" alt="" />
