6. Fingerprints And High blood Pressure
British researchers studied 139 men and women to see what fingerprints can say about blood pressure.
They found that people with a whorl (spiral) pattern on one or more fingers were more likely to have high blood pressure than people with arches or loops.
”The greater the number of fingers with whorls, the higher (is) the systolic blood pressure,” said Dr. David Barker.
This suggests that high blood pressure in adults can be traced to development of the fetus in the womb. (source)
