Scientists have confirmed the new theory of the dark matter of the figure and some parts of the human body sometimes indicate an increased risk of serious diseases: heart attack, stroke, diabetes, and even some cancers. Typically, it is the genes and sex hormones that affect the fetus during embryonic development. Not only the appearance depends on this, but also the predisposition to health problems.
In 2001, researchers from the University of Liverpool (United Kingdom), observing men suffering from heart attacks, noticed: among them, there are many who have a short ring finger. And the greater the difference in length between the finger and the index finger, the earlier heart problems occur – usually around 30 years old. If the fingers are equal, then the heart attack usually occurs after 50 years. And those whose index finger is shorter than the nameless one insignificantly, the first problems recorded only at 70.
Scientists have suggested: everything is to blame for testosterone, which affected the length of the fetus fingers during intrauterine development. In particular, that is why in women the ring finger is usually shorter than the index finger, and in men – the opposite. But in British patients, despite the sex, due to high testosterone levels in the eighth to fourteenth weeks of pregnancy could form a short ring finger. In addition, this resulted in an increased hormone level in adults. And when the body has a lot of endogenous testosterone, blood clots are more often formed and serious heart diseases develop. That’s why, the authors noted, a short ring finger may indicate the risk of heart attacks and strokes at a young age.
It looked logical. And three years later scientists from Cambridge University (Great Britain) confirmed this hypothesis. Watching three dozen pregnant women, and then their babies, they found out: the prenatal level of sex hormones affects the ratio of the length of index and ring fingers.
In men, the ring finger is longer than the index finger. According to a common hypothesis, the level of male and female sex hormones in the eighth to fourteenth weeks of pregnancy determines the difference in length of these fingers in the future child.
However, in 2010, Australian researchers in a sample of 244 women and their children found no such connection. And in 2020, Polish scientists showed that increased intrauterine hormone exposure is not related to their levels in adults. However, British and German experts note: although the high concentration of testosterone during embryonic development does not affect its content in the male body, the production of this hormone increases, for example, during exercise or stress.
From cancer to osteoarthritis
Men with short (relatively index) ring fingers are at risk not only for heart disease but also for prostate malignant tumors. This conclusion was reached by British researchers, comparing 1,500 patients with prostate cancer with three thousand healthy men.
Those with longer index fingers were found to be 33 percent more likely to develop prostate cancer. The authors of the work assume that it is about the genes HOXA and HOXD: they are responsible for both the length of the fingers and the sexual system.
In addition, malignant tumors of the prostate often occur against the background of increased testosterone concentration. This, in turn, may be a consequence of the peculiarities of the intrauterine development – the fetal testicles produce too much of this hormone. This results in the formation of long index fingers, which can be considered a sign of predisposition to prostate cancer.
In women, as a rule, longer index fingers – as compared to the nameless ones – speak of late menopause. But short ones reduce the risk of breast cancer and increase the chances of encountering osteoarthritis in the hands.
Feet from the ears
According to German scientists, long legs are a guarantee of life without diabetes. Experts analyzed the information about the height, length of legs, waist circumference, weight, and health of two and a half thousand middle-aged people. It turned out that an additional ten centimeters to the lowest height value (169.7 for men and 157.8 for women) on average reduce the risk of type 2 diabetes for men by 41% and for women by 33%. Long legs of both sexes have little chance of getting sick, but the elongated torso, on the contrary, contributes to the disease but only in men.
However, the authors of the work warn that excess weight – regardless of what it is caused – levels out the advantages of high growth. Thus, every ten centimeters of thinner ones reduces the risk of diabetes by 86% for men and 67% for women. But in people with excess pounds or obesity, this effect is much less – 36 and 30 percent respectively.
However, owners of long legs are more likely to suffer from malignant tumors of the intestine and colon, found American oncologists. Having studied anthropometric data and medical and medical data.
