The human body was full of mysteries. Scientists in modern times still hadn't answered everything about the secrets of the human body.
Everyone had fingerprints that were different, even identical twins had different fingerprints. It is the diversity of bodies where no one was the same. Some people had dominant hands such as the right and or the left. Some were ambidextrous but still preferred one hand better than the other. People were also born with different talents, such as being able to hear distinct sounds and play musical instruments well but some others were born without musical talent even though their parents were music maestros. There were people who had excellent motoric skills, thus they were extremely skilled in sports and some were able to paint an art spectacularly.
What about blood type?
There were eight main blood groups, but many people didn't know that in these eight blood types, there existed different variations not mentioned often!
