My HormonologyLadies: Take a look at your hand palm-side up for a moment. According to a recent study, if your ring finger is longer than your index (pointer) finger, you’re more likely to have traits that make you a successful entrepreneur—including aggressiveness, determination and a desire to take risks! The reason? A ring finger that’s longer than an index finger is an indication that you were exposed to more testosterone in the womb, which impacted your brain development and makes you more sensitive to the effects of your own testosterone for the rest of your life. As a result, you’re more likely to adopt traits generally associated with testosterone.

While this may sound surprising, this research is just the latest in a string of recent studies examining finger length in women and men. Previously, scientists have discovered that an index finger longer than the ring finger means you tend to be more nurturing, chatty and cautious. And an index finger that’s shorter than the ring finger indicates that you enjoy thrills, take greater risks, have more muscle strength and could be talented at either sports or music. Of course, there’s a lot more that affects your personality and behavior than just finger length, but it’s still an interesting insight into the way hormones have a powerful impact on all that you do!

Tip: For the most accurate finger measurements, measure from the crease at the base of your finger rather than eyeballing the height of your fingertips, since the ring finger is typically set lower in the palm.
