I have got a great idea for a coffee table book for diabetics!
Photos of insulin tubing knots. If I've got pajamas with no pockets, then my pump just lies next to me while I'm sleeping. The next morning, it's often tied up into some of the more elaborate knots you've ever seen. I don't like the belt clips, so I always wear my pump in my pockets, and there, too, does the tubing tend to take on a life of its own. Maybe 45 seconds to unwind the knots. (They're not so tight as to kink the hose and cause occlusion.) Sometimes, even, I give up on trying to thread the pump through the loops, and disconnect the body-end and try to fix the kinks that way.
So anyways, I thought a collection of photographs of the craziest, naturally occurring knots would make for an interesting book to leaf over. Like trying to undo a 100-foot extension cord, but maybe not THAT bad!
It's probably easier to pull off as a website rather than a book, but who knows!
