What's the name of another line? I guess it is the Fate line or Health line.
If the lifeline crosses over the fate line, it means you have a strong vitality and are full of energy. Your social status could be upgraded quickly with your hard working. Even though there is not great achievement during your life, you could be satisfied and enjoy a happy life.
If the lifeline crosses over the Health line, it will be an inauspicious sign for health. You may have a weak cardiovascular system which affects your normal blood circulation.
