Where on your body is your lifeline and line of the heart?

In palmistry, the lifeline is typically found curving around the base of the thumb and encircling the ball of the thumb, while the line of the heart is located above the lifeline, running horizontally across the top of the palm. The lifeline is believed to represent a person's vitality and life experiences, whereas the line of the heart is associated with emotional matters and relationships. The exact appearance and length of these lines can vary significantly between individuals.
