Biological brilliance at work.
Ever wonder what’s really going on inside your head? Quite a lot of voltage, actually. The human brain, that three-pound hub of thought, memory, and creativity, produces about 20 watts of electrical power while you’re awake. That’s roughly enough to keep a small lightbulb glowing, all from the synchronized firing of billions of neurons.
Every thought, memory, or “aha!” moment is the result of electrochemical signals zipping across neural pathways at lightning-fast speeds. Each neuron communicates through electrical impulses, creating a constant buzz of microscopic activity. Multiply that by about 86 billion neurons, and you’ve got a biological supercomputer humming along 24/7.
In tech terms, your brain is a marvel of low-energy, high-performance design; no charging cable required. It’s more efficient than any processor humans have ever built, running complex tasks while consuming less power than a dim desk lamp.
So, the next time you have a bright idea, remember, you’re literally wired for it.
