Complete aside here: I used to do work with amputees and prosthetics. There is a standardized test (and I just cannot remember the name) that fits in a briefcase. It's used for measuring the level of damage to the upper limbs and for prosthetic grading.

Basically, it's got the dumbest and simplest things in it. Stuff like a lock and key, a glass of water and jug, common units of currency, a zipper, etc. It tests if you can do any of those common human tasks. Like pouring a glass of water, picking up coins from a flat surface (I chew off my nails so even an able person like me fails that), zip up a jacket, lock your own door, put on lipstick, etc.

We had hand prosthetics that could play Mozart at 5x speed on a baby grand, but could not pick up a silver dollar or zip a jacket even a little bit. To the patients, the hands were therefore about as useful as a metal hook (a common solution with amputees today, not just pirates!).

Again, a total aside here, but your comment just reminded me of that brown briefcase. Life, it turns out, is a lot more complex than we give it credit for. Even pouring the OJ can be, in rare cases, transcendent.
