Palm reading answer
What does a downward branch from the head line mean?
What this means
First confirm that the branch really starts from the head line and bends downward, rather than being a crossing crease or photo shadow.
Then check whether it gently slopes toward the Moon area or drops sharply, because the strength and direction change the reading.
Read it with the main head line, hand shape, depth, breaks and both palms before making a conclusion.
