Having a face that is more trustworthy than others is something unclear. However, this feature will create a big change in life. Researchers from Israel and the United Kingdom gave volunteers randomly selected images from two photo databases and asked these people to assess the level of emotional state and characteristics. Character and criminal appearance.

The first set of photos is taken from the police crime database database; and the second set of photos of the actors required to appear happy, natural or angry.

The photos of the actors expressing angry emotions are considered the most criminals.

Recently, two psychologists at the University of Toronto collected images of prisoners in custody for first-degree murder for research purposes. Half of them were sentenced to life imprisonment, the rest were executed.

After that, there was a group of survey participants assessing the level of trust based on a scale of 1 ( completely unreliable ) to 8 ( completely trusting ). Those who are judged to have low levels of trust are mostly those sentenced to death.

In another part of the study, respondents were provided with photographs of those convicted of murder but later vindicated ( based on DNA evidence ). However, these people are still considered unreliable even though they were later proved innocent.

In addition to showing age, wrinkled skin also reveals more problems such as current cardiovascular status. A study was conducted in 2012, which compared the number of facial wrinkles to the biceps in 261 people aged 63.2 and 253 at the same age of 62.7. Women at lower risk for cardiovascular disease are described as 2 years younger than their actual age when compared to women at higher risk for cardiovascular disease.

Doctors can diagnose health conditions through the eyes. Red spots in the retina or light sensitivity may be a sign of diabetes. When the blood sugar index rises, this obstructs blood vessels in the retina, causing them to swell and break out to create a red dot.

Scientists studied the finger length of 1,500 prostate cancer patients and 3,000 healthy men over a 15-year period with a request: look at pictures of hands and tell which hands corresponding to them.

Men say that the index finger is the same length or longer than the ring finger, and one-third of them are diagnosed as at risk of prostate cancer. This risk is even higher for men under 60 years old. However, these are just reports based on finger length, not actual measurements, so we should not be too worried when we don't have specific figures.

11. Height also indicates the risk of disease

Recent findings suggest that taller people are at lower risk of cardiovascular disease , while people of modest height often have lower rates of cancer. This depends on the amount of hormone produced, which may reduce the risk of this disease but increase the risk of other diseases. However, these findings do not confirm that the height can prevent diseases.
