👉🖐️ As for the video, your hands may be able to say more about you than you think.

🩸 Iron deficiency anemia can make your nails brittle, which can lead to spoon-shaped nails (koilonychia).

💅 Melanonychia, which is a dark streak in the nail bed, is generally benign and the result of either a mole, trauma, a foreign body, or pigment in the skin (genetic). However, in rare cases, it can turn out to be melanoma (skin cancer). ⚠️

☝️ If your ring finger is longer relative to your index finger, it suggests that you were exposed to more testosterone in the womb and (if you’re a male) may have a higher risk of developing male-pattern baldness. Some studies also suggest it may be associated with increased athletic performance 🏃‍♂️💪.

👍 If you can reach your thumb completely across your palm and past it, it suggests that you have looser collagen and may be at an increased risk for an abdominal aortic aneurysm ❤️🩻.

✋ Lastly, if you do not have a palmaris longus tendon, you are one of the roughly 15% of people who are missing it. 🤯
