Water and a bubble on it are one and the same. The bubble has its birth in the water, floats on it, and is ultimately resolved into it. Likewise, your consciousness is born in your brain, goes through various states in your lifetime and ultimately resolves into the brain.

Every single decision of your life is predicated on the healthy functioning of the prefrontal cortex. Even a slight malfunction in a tiny chunk of neuron anywhere in the PFC would lead to the mental deficit in your logical decision-making.

Freedom of will is born from the neurons. And that freedom allows you to sometimes make even the worst decisions ever in your life. And by making the worst decision, you simply learn what would be the better decision in future.

We are but a bunch of neurons.
