The life line arcs around the base of the thumb. A long, deep, unbroken line is traditionally read as robust health and vitality. A short or faint line? Nervous energy or a constitution that needs care. A line with islands or chains suggests periods of illness or low energy.
Some palmists also look for a health line (also called the Mercury line) running from the Mount of Mercury toward the life line — islands or breaks here supposedly indicate liver or digestive issues.
None of this has any medical standing. The life line does not predict when you will die. It does not predict cancer, heart disease, or accidents. And telling someone their life line looks "dangerous" is not only incorrect — it can be actively harmful.
