We do not know everything about our body, because scientists have no yet to give a correct explanation about some of the human body. In this report, 8 unrelated mysteries of the human body were discussed.
1.Why do we have fingerprint?
We all know, our fingerprint is so unique that the fingerprints of both are not the same, even in the identical face of twins. But why there is such a rotating pattern on the human finger? For many years the scientists have come to believe that fingerprints help to grip somebody, but later it is proved that fingerprints cannot interfere with many parts of the skin, compared to that smooth fingerprint can grab any object perfectly. So there is no connection to fingerprint with grasping. There are some theories about the evolutionary significance of these unique patterns, such as they protect our fingers or provide touch sensitivity. But scientists have not yet made any definite explanation about this.
2.Why do we have an appendix?
Appendix is an organ that gives a lot of pain to many people, and removing it does not affect our body. Appendix may cause more problems than its importance. For many years, scientists agreed that appendix is necessary for digestion of plant-eating ancestors, but it has no real work for modern people. Recently, another theory has gained popularity in the scientific community, claiming that the tube-like organism provides shelter to many beneficial bacteria and protects them. We have to wait until this theoretical evidence to dispel the uncertain concept of Appendix.
3.Why do we have a major hand?
We are accustomed to a Demand Hand or Head, and on this basis the right hand or left hand is determined. But why does one hand work better than other hands or feel more relaxed? Why can not both of us be equally efficient? It is still one of the biggest unresolved mysteries in the human body. Although some people can work in both hands with equal efficiency.
4.Why do we have different blood groups?
People of different blood groups like Appendix also provide clues to our evolutionary history. Different blood groups have the ability to inactivate various infections and scientists believe that about 20 million years ago, blood group was formed between the ancestors and other wild beasts of the human species. Muhammad Mobayed, a doctor of the Proemediko Hematology / Oncology Associates, said, "The combination of certain types of blood and natural selection against some infections has created a blood group of wonderful diversity among people, which we are seeing in this age." But scientists have not yet been able to know the exact cause of blood groups. Dr. Mobayed said, "There is no proven theory about why people have different blood groups."

5.Why do we dream?
Maple Holistic's health and wellness expert Calab Becky said, "People spend about a third of their life sleeping and scientists are still very little known about how and why we dream about it." We know that during the Rapid Eye Movement slip we dream and dream Heartburn increases while watching, but we do not know which dream arises for some purpose. A popular theory is that during sleep, which is one of the important memories of the day by the brain and the selection process is the dream process. Another theory is that dream is not really a work, but it is the sleeping state of our unconscious mind.
6.Why do we have virus inside our body?
There are many microbes or germs in our body which weighs a few pounds of our body weight. Many microbes in them benefit our body- they help digestion, heals wounds or warms the disease. But most microbes are viruses and scientists are still not aware about the purpose or work of these viruses.

7.Why are other primates stronger than us?
Similar to chimpanzees, there is a similarity between people in many areas, such as the composition of humans and other primates muscles. Nevertheless, our closest primates are 1.35 times stronger than ours. We have a slow-tissue muscle fiber which is less powerful than other primates. Our muscle fiber is much more tolerant than other primates, that is why a man can not run a marathon even though a marathon can run. But scientists have not yet identified the reasons for the inequality of energy among humans and primates.

8.Why smiling touches?
Yes, smile is contagious and it is not only in metaphor. Scientists have discovered that strong emotions enable different people to be infected at the same time. Dr. Bucki said, "It is found in the study that there are social relationships related to laughter. In fact, psychologists have discovered that people laugh about 30 times more in social situations. "He adds," The convention is that human beings are infectious because they are sympathetic creatures. "When we smile, our brain releases endorphins and this chemical is safe for us. Helps to feel comfortable. The real reason why laughter is not yet revealed
