Why is it that right before you go to bed you think uncontrollably? Tonight I was thinking, we humans are kind of like machines, well products. We are all consisted of the same parts, two legs, two eyes, a brain, a mouth, etc. (excusing those with abnormalities, though every product is bound to have a defect) Yet not one person is like the other, sure there are similarities but no one is exactly the same. We think differently and act differently, but how is it that we are made by the same parts, and fueled with the same blood but are different? What exactly is the “ingredient” that segregates us from each other?
