The Parable of the Electron
There is an infinity of space between two molecules, even between two atoms as tightly knit as the ones in your cramping chest. It would be foolish for an electron to jump between the two and even if it did, if it embarked on this suicide mission, it would be ludicrous to expect its friends to follow it. It would mean an eternity of loneliness just to reach that other atom, to orbit it a little while. It is absurd for the EMT to apply the defibrillator to your chest, it just means loneliness in the back of the ambulance.
