but the person is influenced by moon ! how can his or her lines be just the same ! the person would think a lot . making a lot of difference . though the person is of material world [ nature ] but still moon makes one think . i wonder !

Wow thanks for the insights. I am a 31 year old female. I completely concur with the not changing since childhood part. I just had never thought of it like that before, but it's entirely accurate. Although I cannot say it's been without some improvement. And I would never want to go back

I wasn't trying to scourge a free, multi-palm reading from anyone here, and I apologize if I made it seem as such. The X's bothered me, was all. And surprisingly, I searched the internet far and wide for why both palms would have the same markings, but there really was nothing relevant. Though I did learn a lot about simian lines.  
So thanks for taking the time to answer my questions. If anyone has any other input about the X's (they are obviously in both lifelines, same places), please feel free to share.

Take Care

add: I wasn't aware that a person having the same lines was a rarity or important. I still don't know if it is, and again, I don't want you all to read my palms for free or take extra time, I just joined the forum after all. But if you want to see both hands just for personal curiousity, I don't mind posting them

oh , the x , it is just the mercury line or health line or digestion line getting displaced by some amount , it means that at age of about 60 you would have a relatively big digestion problem .

when a human being interacts in any way with another person , a part of others soul get stuck in each ones soul . it causes change in human beings .
