I take this power for granted, but I don't have a clue how it works.
If our technology were to disappear tomorrow I wouldn't be able to do a thing to get it back. I don't even know how to smelt metal.
Maybe I'd have the wherewithal to go make myself a hand-axe, though I understand there's quite an art to knapping flint.
Left to my own devices I belong in the stone age- if that.
I have about as much aptitude for tool-making as a chimpanzee.
