Is it credible to read palm print fortune telling? What is the basis?

I have a foundation in reading palm prints, but I don't know fortune telling. Palmprint will change according to physical condition and age. You can look at them carefully. You can tell a person's physical condition by looking at the palm print. You have just read a book, which is described correctly, and your personality can be seen. However, in any case, you can change your life by your own efforts, and what the fortune teller said can also help your psychological will. Everything still depends on yourself.
