Well, if you believe in palmistry, or palm reading, it means that your heart line and your head line are converged, so where most people are divided between what their heart wants and what their head wants, people with conjoined heart and head lines means they have do division within them, so they pursue things with abnormal commitment, and thus their lives usually have high peaks and deep valleys because they fully invest themselves in everything they do with their entire being, so when things go wrong they go really wrong and when things go right they go really right. From Wikipedia (Detailed): "
- A simian crease, or fusing of the heart and head lines, has special significance in that both emotional as well as reasoning nature have to be studied from this line alone. The peculiar line is thought to be a combination of the head and heart lines on such hands that are separately marked on the rest of the hands.
According to Cheiro[citation needed], this line is thought to endow a person with an intensity of purpose or single-mindedness, the nature of which is decided upon by exact position of this line on the hand and the direction of any branches shooting from it, which is normally the case. In hands where such a line exists without any branches as a singular mark, it indicates an extremely intense nature and special care is needed for such persons. The normal position for the line is starting below the index finger and ending where normally the heart line terminates at the edge of the hand below the little finger, indicating average interests for the person and the intense side of the nature is decided purely by the direction of any branches shooting from it.
The upper half of the palm lying immediately below the fingers is considered to represent the higher or intellectual nature and the lower half of the palm to represent the materialistic side of the nature. If one of these halves is larger than the other as decided by the central placement of the head line or in this case the single transverse palmar crease it shows greater development of that aspect of the nature. Based on this general principle, if this line is placed below its normal position it indicates an intensely intellectual nature; if it is placed above its normal position it indicates an intensely materialistic nature and interests.
The direction in which any branches may be found shooting from this line have a significant impact on the nature of this line resulting in suitable modifications from the above defined results depending on the nature of the mounts on the hand. For instance, if a branch from this line shoots to the mount of Moon lying on the lower edge of the hand exactly opposite the thumb, it indicates an intensely vacillating nature and emotional temperament."
and from a kinda ghetto website (Simplified):
"Palm readers and Hand Analysts have observed over the years some common traits in people with Simian Lines on one or both hands. [This pertains to those people who have no apparent medical problems.]
People with Simian Lines generally live their life differently than most other people who do not have Simian Lines. Not necessarily living better nor worse. Just living more intensely with an undercurrent of uneasiness. It is interesting that a number of well-known people with a Simian Line have made a positive contribution to history. They include British Prime Minister Tony Blair (both hands), former Russian President Nikita Kruchev, writers John Steinbeck and Henry Miller, Tony Robbins, and Hillary Clinton."
