In simple words
The life line curves around the base of your thumb. Palmistry links it with energy and vitality. It does not show how long you will live.
How to recognise this one: The curved line around the base of your thumb swings well out into the palm, enclosing a large area.
What it means
You have plenty of energy and enthusiasm for life. You enjoy adventure, take opportunities as they come and recover well after effort. People are often drawn to your vitality. The life line describes energy and enthusiasm, not the length of a life.
Growth
Pace yourself so your energy lasts. Rest is what keeps a strong fire burning.
Palmistry is a tradition of reflection, not a medical or scientific reading. Lines change over a lifetime, and no line predicts illness or the length of a life.
