What do the three lines on the palm of your hand mean?

What do the three lines of the pattern represent, as shown below:

1. Lifeline: It starts from the index finger and thumb, is parabolic, and extends to the wrist. The longer this line is, the better, and the longer it means the longer life.

2. Brain line: Also known as wisdom line, starting from the lifeline, it is a line that walks in the middle of the palm and ends at the thenar. As long as people with mental retardation and dementia are thin and chaotic, they can't be a clear line.

3. Emotional line: The emotional line starts from the palm of the little finger, bends in the direction of the index finger and reaches the gap between the index finger and the middle finger.
