For me it is the fact that our blood contains iron. I earlier used to believe the word stood for some 'organic element' since I couldn't accept we had metal flowing through our supposed carbon-based bodies, till I realized that is where the taste and smell of blood comes from.

It gets better. The size of the SD card isn't the storage area. Look carefully at the back of an SD card and you should see how a tiny square area in the middle is a bit 'thicker' than the rest; that's the actual chip, that tiny bump!

    SD cards make sense to me. Hard Drives... Now there is some spooky technology.

    The reader head on a hard drive changes direction so fast, that it experiences accelerations like that of a bullet being fired, hundreds of times a second.

    The "Fly height" or distance a reader floats above the platter is so tiny, that it would crash into a thumbprint.

    The actual magnetic media that stores your data is a layer of iron a few atoms thick deposited on to a ceramic or glass platter, with a single atom layer of a protective metal coating (typically rhodium) in top of it.

    Despite these incredible tolerances, they damn things are dirt cheap, and surprisingly reliable.
