It just got me thinking that almost anywhere you go, you can find some clever person designing new uses for everyday objects. These inspirational designs can get you started on a road of your own. So, we went from Megacon, to steampunk butane ladies 'plasma' gun to isn't that a clever little personal defense weapon that looks harmless and fashionable?
Speaking of harmless and fashionable. I am teaching my grand daughters to have some jewelry about their person, not too flashy, but of precious metal, should cash become futile. I used to have a collection of "poison" rings when I was a teen. Now I only have two. I know they were originally for secreting poison to do away with the king. They are great to tuck away an aspirin in. If you need to carry a glycerin tab with you, this is real handy. It is also fashionable and they are not hard to find in men's styles, too.
Looking around your life and learning how things go together is good for you. The mind needs exercise. The spirit needs a break from the fear factor of preparing for the of end of days. Look how things are made. Learn how to make them when there is no one else to produce goods. Redesign them for fun or for better use in self defense. Take a break and create something of your own.
