I read a lot of palms and said that I would not live to be 50 years old.

Palm reading can't determine a person's life span, which is impossible to budget. People's acquired behavior can change innate numerology. Doing more good deeds, paying more, releasing more, accumulating more virtues, and being kind to everyone around you can increase life expectancy. Don't trust faces too much. Face is a kind of statistics, and its highest accuracy rate is only about 80%, not 100% accuracy. The result can only be believed by reference, and fate will always be repaired by itself. People's destiny can be changed. I suggest you take a look at Fan Sixun.
