Can the length of your ..... finger predict your running ability? Yes it can.

Opposite for me. My left (non-dominant) hand has ring longer than index. But right has index a fair amount longer than ring.

Could be you're both non-binary.

Say it again 😭

Can the length of your...penis? Yes it can!

Right!

fingers, it is a measure of testosterone.

you don't need to look at hands however, to know who has testosterone and who does not.

still it is a fun fact.

Hey ladies!

The distance between the tip of the index finger and the tip of the thumb when those two fingers are spread apart as much as possible equals the lenght of a man's erect penis. When the hand's laid out rested on a flat surface the same distance equals the lenght of the same penis in its rested state.

In case you didn't know already.

How do they measure the fingers - knuckle to tip, or inside of webbing to tip? My ring finger has webbing that would impress a duck

Both of you have such differently sized finger lengths? Mine are pretty identical. Index finger reaches the cuticle of ring finger.

Hey Rojo, my middle finger is longer. What does that mean?

This is BS. My ring finger is bigger than my index finger and I barely broke 3 hours in the marathon.

It's almost like there might be other factors involved, like training, weight, overall health habits, etc. Maybe Rojo can find a study on those.

My ring finger (on both hands) is longer than my index finger too - and I'm a woman (the female kind). So I've never put much stock in the claim that having a longer ring finger than index finger is a sign of "higher testosterone exposure in the womb."

Does that apply to “Morton’s Toe” as well. I have a pronounced case of mt but little to show for it. As to the other thing, the rule seems to hold up for me.

That puts you in the top 1% of the Worlds population - think about it! ;-)

This topic is related to sexuality too. While old, it’s correct that 2D:4D is often linked to athletic ability because it’s thought to reflect prenatal testosterone exposure, which can influence traits like muscle development and spatial awareness. But it’s also been studied in relation to sexuality. Research shows a moderate correlation in women, where lesbian women often have a lower (more “male-typical”) 2D:4D ratio compared to straight women, with a higher ratio presenting estrogen exposure. In men, though, the evidence is much weaker and inconsistent. So while the link is clearer in women, it’s far from a sure thing and not a reliable indicator of sexual orientation in either sex.

Rent free 🤡

Oh God! My index and ring fingers are almost exactly the same length! FVCK!!! I'm barely a man! The world has conspired against me! It isn't fair!

I used to have confidence; my running/lifting/penis PRs are all in the 95-99th percentile. But this new information has left me shattered. I may need to resort to cosmetic ring finger-lengthening surgery. I am typing this with ski gloves on to hide my newfound shame.

Exactly what I’d expect a 2:50 marathon guy to post
