The human body is an engine that needs a lot of tlc. The food we eat and the air we breathe gives us the energy to power this engine. When organs are refreshed, glands are re-vitalized, and muscles are re-trained, the body produces an inner heat that uses up excess calories.
But like all engines, our body needs to be fed, cleaned, watered, and aired from time to time to stay functional. The various systems are so inter-dependent that, when one fails, others are impacted too. That is why it is vital to develop a routine that mobilizes the whole body.
