A study found that the longer the ring finger than the index finger, the more likely it is to drink alcohol.

The ratio of finger length reflects the influence of hormones in the mother's womb before birth, which may be associated with post-adult drinking behavior.

According to the study, finger length is affected by testosterone and estrogen, which the fetus is exposed to in the uterus.

If the testosterone level is high, the ring finger is longer than the index finger, and if the testosterone level is low, the ring finger is shorter than the index finger.

This study showed that if testosterone levels are higher than estrogen, alcohol intake may be higher afterward.

The Swansea research team in the UK recruited 258 participants (169 women and 89 men) and then measured the length of their fingers to see if the length of their index and ring fingers was related to alcohol consumption.

In addition, the World Health Organization (WHO) enacted the "Alcohol Use Disorder Screening Test (AUDIT)" to evaluate the degree of alcohol consumption among participants.

The research team analyzed the link between finger length and alcohol consumption and found that the shorter the index finger than the ring finger, the higher the frequency of drinking and the greater the risk of problematic behavior due to drinking.

In particular, this correlation was more pronounced in the right hand than in the left hand, and this association was stronger in men than in women.
