Imagine that, for whatever reason, you identified as your mind and thus your brain. You didn't think of your body as much more than a "meat mech" that your mind/brain piloted.
You would do brain exercises and take nootropic supplements, but you neglected your body and became unhealthy. Then one day you have the realization that your brain needs the rest of your body to live, and everything is interdependent.
You stop identifying with the mind/brain and embrace your whole body as yourself.
@Tfmonkey Technically all nerve tissue is a form of brain tissue, they are mechanistically identical. If someone loses a limb they are losing a portion of their brain. Once one see's the brain not as a singular organ thats plugged into the spinal cord, but rather as a central core of an otherwise decentralized system of thinking, it changes ones perspective of biophysics. Biology is an absolutely fascinating subject that I hold immense reverence for even though its outside my domain expertise.
