The head line (also wisdom line or intelligent line) is the second important line in palm reading. It starts from the palm edge between the thumb and forefinger, and extends across the palm in the middle part with the life line below and the heart line above. The head line reveals a person's wisdom, belief, attitude, thinking ability, strain capacity, creative ability as well as abilities of memory, self-control and more. In general, a deep and thin head line is good for a person. If you have such a line, it indicates you are smart.
