Before the discovery of DNA information in the 1980 s,fingerprints(指纹)were the easiest
way to solve serious crimes.It's believed that each one of us has our own fingerprint.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 with the eye and require a chemical development process in order to make them shown.
Stuck between the raised lines of a fingerprint 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 fu t ture for
doctors to treat 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 by the police and help doctors keep us in the
best possible health.
