I think simian lines are an interesting phenomenon. A prominent singular horizontal crease on the palm, taking the place of both the heart and head lines that most people tend to have. Aside from having a high correlation with various genetic disorders, it is meant to be very rare to have this, even more so on both palms.
While I don’t give any credibility to traditional palm reading, I find the personality profile for people with simian lines interesting, as it matches me disturbingly with uncanny accuracy. Unlike most palm readings or horoscopes, the descriptions are not so vague as to be able to apply to anyone (although they are still somewhat abstract). The sole reason that I think there may be something to this is that a physical marker could perhaps correlate with certain personality traits. This seems at least possible, while standard palm reading or astrology is based on nothing.
According to western interpretations I cannot separate my thoughts from my emotions, as thinking and feeling is the same thing for me. I don’t know if I would go that far, but I definitely feel like my emotions are a byproduct of my consciousness as opposed to something innate. Other personality descriptions are that I am more intense than normal…while I would not have thought so it is something I get told frequently. Apparently I also have an increased stamina and a propensity for either great success or great failure. According to Chinese astrology, a double simian line means I am extraordinarily intelligent. It is unlikely any of these descriptions are accurate, but it interesting to think about. I just hope the correlation of simian lines and heart defects is meaningless.
There doesn’t seem to be a lot of info on simian lines online, and I got most of my information from the top few search results which tend to be mystical in nature, which are still entertaining to room. If anyone has more information on simian lines from a more reliable source, I would appreciate a link.
