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 life line has a gap, or one section ends while another begins slightly to the side.
What it means
Breaks are common and are usually read as times when your outlook or way of life changed: a move, a new direction, a fresh start. An overlap suggests the change was well supported. Lines on the hand also change over time.
Growth
Look back at the changes you have already handled. They are proof of your adaptability for whatever comes next.
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.
