The human body is a marvel of complex systems and intricate processes. It is made up of trillions of cells that work together to keep us alive and functioning. Our hearts beat around 3 billion times in a lifetime, pumping blood through our veins and nourishing our organs with oxygen and nutrients. The brain, the control center of our bodies, uses an estimated 20% of our total energy expenditure while accounting for only about 2% of our body weight. It is responsible for controlling everything from movement to emotions, thoughts, and sensations.
