Have you ever been swimming on a hot day at the lake? You step into the cool water, wading further in, immersing yourself deeper with every wave. You close your eyes, take a deep breath, and dunk your head under. When you emerge with your eyes still closed, the heat from the sun beams onto your face emulating joy in a way you’ve never even imagined before. This is the physical manifestation of happiness, of that I’m sure.
