humans have 206 bones in their body by the time death is waiting to drag them off. there are 28 alone in your skull alone, 33 bones in your spine. 24 ribs - 12 on each side, and 30 bones in each of the arms and legs. Bones give us structure to walk, to protect vital organs.. lungs, kidneys, stomach, brain, intestines. You think that'd be enough. The heart is the strongest organ in the body. It pumps blood to all of the organs, everything needed to live.
it's extremely important.
But the brain controls our emotions, why do people associate them with the heart? Is it because it's so strong? It's because the heart is easy to puncture. Because the heart is the center of our lives. Just one strong blow to the heart is enough to kill you in seconds.
I guess emotions are the same.
