Delhi, January 30th. Delhi experts have established that a sick person is given external signs that even ordinary passers-by, not just doctors, can identify. The materials of the study are placed in the journal Proceedings of the Royal Society B. As noted by Delhi specialists, the ability to pinpoint behavioral or physiological characteristics by external features will help to avoid threats and unpleasant situations.
During the experiment, researchers checked how quickly and well a person can identify a patient by external signs, including a person, not a cough or a runny nose. For the study, all the respondents were shown pictures of volunteers infected with endotoxin and suggested whether the person was sick or completely healthy.
It turned out that the test participants in 62% of cases accurately determine the sick person. Among the noteworthy features polled called pale lips, swollen face and swollen eyelids, as well as reddened eyes.
