Hello, sorry the age was a mistake. Okay, I read the same thing in Benham's Book of Palmistry lol. That exact information is the information that confused me. That is why im on this forum to seek teachers/experienced help. Please look at my hand and help

.
Also would anyone be able to help me tell which plane of the hand as a whole my hands fit? I dont understand how fingers can be "developed" or throw off "balance" and I dont understand how development of the different planes can be compared to see which is dominant. Please help!
