    It’s so they can fold easier. Notice when you fold your hand it folds along those lines.

    They are caused by folding. Just like folding a piece of paper makes a wrinkle in it.

    If you have a rare condition that makes your hands immobile, they do not get lines.

    When you fold a soft material it has to have a seam line somewhere. Your skin gets a bit more stress in the seam line and somehow changes and has a bit more elasticity. The next time you fold your skin it will naturally fold where it is more flexible and a feedback loop starts. People that are born with immovable fingers don’t have a seam line there.

    1. Он полагает печать на руку каждого человека, чтобы все люди знали дело Его.

    УПО: Він руку печатає кожній людині, щоб пізнали всі люди про діло Його.

    KJV: He sealeth up the hand of every man; that all men may know his work.

    ( Keep the same pattern on the left and right hands. Your goal: if you do everything right (by keeping the Golden Rule and being nice to others).
