What does that mean?

In addition to your hair color, your body is full of all sorts of clues about your health. Here’s how to decipher those codes:

Being tall

Dutch researchers from Maastricht University found that a woman’s chance for developing breast cancer increases seven percent for every half inch over 5’7”.

Having dark skin

A study from Pennsylvania State published in Pharmacology shows that people who have a dark complexion are more susceptible to nicotine dependence. That’s because the melanin, which is responsible for your skin’s coloring, slows down your liver’s ability to metabolize nicotine, making it stay in your system longer — and leaving you more likely to become dependent on butts.

Long ring fingers

You’re more likely to develop osteoarthritis, according to researchers from the University of Nottingham and the University of South Florida. The scientists found that this was especially true for women, who usually have equally-sized ring and index fingers.
