Finger length ratio.

[pjoshea13]

New study below [1].

The study of finger length ratios may seem as wacky as palmistry & phrenology, and certainly not something that should have survived into the 21st century, but ....

The ratio between the lengths of the index finger (2D) & ring finger (4D) is affected by the ratio of testosterone to estradiol in the womb. ("The 2D/4D ratio at the age of 2 was found to be negatively correlated with the testosterone/oestrogen ratio as measured by amniocentesis in the second trimester" [3])

Surprisingly, the 2D:4D ratio correlates with being good/lousy at sports & much else. A low ratio increases PCa risk, whereas a high ratio means more heart disease.

Chances are, members of this group have a longer ring finger [2]:

"Pattern of finger lengths may be a simple marker of prostate cancer risk, with length of 2D greater than 4D suggestive of lower risk."

[3] "The 2D/4D ratio is related to adult testosterone levels and the presence of testosterone deficiency syndrome. Patients with high 2D/4D ratios have lower testosterone levels and higher risk of testosterone deficiency syndrome."

[4] "The PCA group presented significantly lower right and left 2D:4D ... in comparison to healthy controls"

In the new Chinese study [1]:

"Digit ratio may not only have predictive value in risk but also prognosis of prostatic cancer. This finding suggests that low 2D:4D can be used as prognostic factors to identify patients with a poor prognosis. These patients may benefit from more aggressive management."

...

I wonder how one obtains funding for such studies?

Perhaps our own data could advance the science of PCa anthropometry? LOL

So Patrick, you got me checking out my hands very closely. What I discovered was my left index finger is a full 1/4" shorter than my right index finger. I thought I would have figured that out long before now. But I'm right-handed, that's a good thing, right?

While checking it does seem weird giving yourself the finger (and especially when you're not driving).
