You and I, we are living creatures. We have a heart that beats, blood that flows through our veins and brains that work. We have eyes and ears that observe and take in lots of things, feelings within that respond and all this held together by our skin. We have this well-oiled system that works together. That can keep working together because we nourish it with what it needs. We give it oxygen, food and water. It’s all that we basically need to survive, right?
