Your fingerprints reveal more than you think
Summary
We know that all people have different fingerprints, even the identical twins who are alike in all ways have it.
According to my research on the internet, in 1788, the German anatomist Johann Mayer seemed to recognize that fingerprints are unique to each individual. Some Europeans published books about fingerprints before it, thus I thought that the speaker must be European. That was right, hahaha. 

In fact, in Japan, the fingerprints were used for recognizing each individual from the Edo period. From 2007, foreigners entering Japan will be required to be fingerprinted and photographed during their entry procedures to preserve the peace in them and Japan.

And then, people leave a little piece of fingerprints behind on every surface that you touch. They think that the fingerprints are too small to see and too many to recognize whose fingerprint it is. However, in the modern age, by helping the computer, it can be presented on only one person print from many.
Our fingerprints are made up of molecules. We produce seat molecules in very different amounts that are using not only blood, paint, and grease but also invisible substances. Thus molecules are who we are, it knows about what we did, and there is information on our health, action, lifestyle, and routines there.
