What does fortune telling mean when you are 59 years old and can't believe it?

A master said that a person can't live beyond 50 years old. Can you believe it?

I really can't believe that I'm 46 years old. That year, I really came here in fear. If his calculation is really accurate. It's no use being careful. I can't live either. Later, I also asked him, and he said that I met an expert and solved it. I don't believe what he said afterwards. It is estimated that all the so-called masters earn their living by cheating.
