The heart is a pump. We need blood to carry nutrients and oxygen to every cell in the body and carry away the waste and carbon dioxide. The heart moves the blood through the blood vessels just like a delivery route.
We have a heart to know when we are happy and when we are sad. It helps us recognize what we need; it helps us find the people who give us what we need and whom we can give what they need. Our heart drives our soul; without it, we could accomplish nothing of value.
We have a heart to know how to be selfish. When you think about what your heart tells you, carefully determine if your heart is telling you things that are good for you, or things that are good for other people. Do not confuse these two. Having a heart let's you know what others want, and lets you twist them to your desires.
we have a heart to breath if we don't have a heart we can't live.
