Magnets.
Stop saying magnets!

You can’t just blame the whole apocalypse on magnets!
Oh really? What caused it then?

I don’t know! But that doesn’t automatically make magnets the answer.

Why not? They’re what makes everything else I don’t understand work.

Computers, phones – that’s all magnets. And credit cards and science and… and cows.

Cows!?!

They take a field of grass and turn it into a bottle of milk.
If that’s not magnets, I don’t know what is.
