Although the fingerprints never change,the palmar lines a and markings change throughout life.It our future was all mapped out for us,surely the lines would stay the same.When looking at a hand,we see the person as they are NOW,bringing their past with them and sowing seeds for the future. Although many palmistry do make predictions,any prediction from the hand is only potential.Most prediction is based on the direction you are going in now.It is not set in stone-we all have free will to make choices and changes in our lives,that will affect our future and alter our "fate",and our lines will change accordingly.
