Researchers from Poland and the UK conducted a study revealing that the inclination towards alcohol consumption correlates with the ratio of the lengths of the index and ring fingers. The findings of this research were published in the American Journal of Human Biology (AJHB), as reported by Tengri Life, referencing N+1.
This ratio indicates the influence of sex hormones during the prenatal period: an excess of estrogens increases the length of the index fingers, while testosterone affects the length of the ring fingers.
The study involved 258 students, of whom 169 were female. The researchers collected data on the participants' lifestyles, with particular attention paid to their alcohol consumption. Additionally, the authors analyzed the finger lengths of the subjects.
The results indicated that participants with a longer ring finger compared to their index finger generally exhibited a stronger urge for alcoholic beverages. The researchers also noted that men were more likely to possess longer ring fingers.
Male participants with this characteristic, as the analysis showed, not only consumed larger quantities of alcohol but also faced a higher mortality rate from alcohol-related diseases.
