Before the discovery of DNA information in the 1980s fingerprint(指纹) science was the easiest way to solve serious crimes. It's believed that each one of us has our own fingerprints. But did you know that our fingerprints could show a lot about us?
According to the expert, fingerprints can show lifestyle and environment, eating habits, possible medical problems and even the job of a person.
So how can we work all this out from just a simple fingerprint?
Well, a fingerprint is formed when a finger touches a surface. Most fingerprints can't be seen to the eye and require a chemical development process in order to make them shown.
Besides, its use could be much wider. For example, it may be helpful in the future to doctors treating their patients. A fingerprint exam may also tell a doctor whether a patient is properly taking medicine. In the treatment of some of the most serious illnesses, taking proper medicine is important.
In the future, finger print science can be used by the police and help doctors keep us in the best possible health.
