Food for thought

We accept the fact that our hearts beat because of an electrical signal that triggers the heart muscles to contract. That signal is electrical, and is a result of the shifting of sodium, potassium, hydrogen, calcium, and other chemicals in and out of cells. If our hearts work this way, why is so far-fetched to think that our brains and bodies work this way too? So, when it comes right down to it, we are all electricity, all energy in motion.
