Question

    Before the discovery of DNA information in the 1980s, fingerprints（指纹）were 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 Conversation, 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. Stuck between the raised lines of a fingerprint, however, are things that can tell a story about who we are. Things like sweat, blood, and food show a lot of information about us.

Besides, its use could be much wider. For example, it may be helpful in the future to doctors treating their patients. A fingerprint check may also tell a doctor whether a patient is properly having a medicine. In the treatment of some of the most serious illnesses, having proper medicine is important.

In the future, fingerprint science can be used to the police and help doctors keep us in the best possible health.
