Long or deep
A long, deep line is traditionally read as steady energy and resilience.
Curves around the base of the thumb
The life line
Governs vitality, physical constitution and major changes of circumstance.
Short or faint
A short line is read as concentrated rather than diminished vitality — and emphatically not as a short life.
Breaks and markings
Breaks and overlaps are read as changes of direction: moves, career shifts, illnesses recovered from.
Worth being clear about
The length of this line does not predict lifespan. A 1990 study comparing palm lines with age at death found no correlation whatsoever.
