My favourite version of this tradition is the least mystical. In many rural cultures the marks people actually discussed were the practical ones: the callus of a particular trade, the scar from a specific tool, the stained nail of a dyer or a gardener. These were read openly and accurately as a record of what a person had done all day for thirty years. That is hand-reading in its truest form, and it requires no belief at all.
Is there anything real behind these traditions?
Not in the sense of prediction — no mark on your skin knows anything about your future, and any tradition that claims otherwise is telling a story rather than reporting a fact. What is real is the value of a structured prompt to look at yourself: a framework that asks whether you overextend for the people you love, or whether your public self and private self have drifted too far apart, tends to produce useful thinking regardless of where the question came from.
How should I use this kind of folklore without taking it too seriously?
Treat it the way you'd treat a well-chosen question at a dinner party — as something that opens a conversation rather than settles one. If a reading resonates, ask yourself why that particular description landed, because the resonance is information about you, not about your skin. And keep the two categories cleanly apart: symbolism belongs to reflection and stories, while anything changing on your body belongs to a medical professional, promptly and without embarrassment.
