Every human being is the same, has organs, red blood, hair, skin... Then, what distinguishes humans?
Seeing from my point of view, distinguishing humans is quite easy, just need to know their nature. Of course, this is based on the mindset of each different, so it can be determined how the differences between one human and another.
A good mindset will make the whole body good too. Take, for example, person A diligently exercising because he knows that his body needs good stamina. This is based on his thinking, to do the sport. It will make the body good, and stamina can be prime.
Or maybe person B. Person B is lazy, often sleeping in his room all the time. This makes his body often feel sick, because of the result of just lying in his room without wanting to exercise. He has been back and forth to the hospital several times. His body is sometimes very tired, even though he doesn't do any activity, just lies down.
