Your left and right hands are not identical. They never were. Handedness, use, and genetics all play a role. The dominant hand (right for most people) typically has deeper, more pronounced lines because it is used more. The non dominant hand often shows fainter lines.
Traditional palmistry adds a layer of interpretation. In many schools, the left hand is read as potential, innate nature, or what you were born with. The right hand is read as actualised life, what you have made of that potential.
The anatomical explanation is simpler and better supported. Lines change with use. The more you use a hand, the more its creases develop. That is not destiny. That is friction.
