That’s a fun concept! Thumb shape analysis, like many forms of palmistry, is based on ancient ideas and offers an interesting way to reflect on personality traits. While it’s not scientifically proven, it can still be a playful way to think about how we see ourselves or others. For example, if you have a straight thumb, it might make you think of your leadership qualities, or if you have a flexible thumb, you could feel more aligned with being adaptable and creative.
