Line of Life
(The). In French, La ligne de vie. So also, line of duty, La ligne du devoir, etc. In palmistry, the crease in the left hand beginning above the web of the thumb, and running towards or up to the wrist is so called.
The nearer it approaches the wrist the longer will be the life, according to palm-lorists. If long and deeply marked, it indicates long life with very little trouble; if crossed or cut with other marks, it indicates sickness.
