Hooray for science, which informs us that a smaller ratio between the index and ring fingers “is linked to a longer stretched penis size,” according to research published in the Asian Journal of Andrology. Not only that, but finger length may be able to reveal all sorts of things: “The ratio between the second and fourth finger is related to sperm count, likelihood of heart attack, hand preference, facial masculinity and more” — including likelihood of prostate cancer occurring. This is all related to testosterone in the womb, which seems to have an impact on the distance in length between the fingers as well as on genital size.
About that. Via NBC,
The average ratio between the two fingers was 0.38 in. (0.97 cm), with a range of 0.35 to 0.44 in. (0.88 to 1.12 cm), making the differences hard to make out with the unaided eye. But the lower the digit ratio, the study found, the longer the penis was likely to be.
In women, the index and ring fingers are generally the same length, while in men the index finger is generally shorter.
Now, please stop staring at everyone’s fingers. At least pretend to make eye contact. Jeez.
