brainstem
Brainstem is the unassuming guardian of the brain that tirelessly maintains the two great lifelines of breathing and heartbeat even while consciousness takes a break. Behind the glamorous stage of emotions and thoughts, it steadfastly keeps the survival switch flipped without ever seeking the spotlight. Occasionally it malfunctions and orchestrates a literal grand finale to life as a silent dictator. In short, it is the hidden sovereign seated on the throne that upholds our very existence.
