What does short-lived fortune telling mean on the Internet?

Once I was walking on the road, a fortune teller came over and told me that life is short and let me do the math. I ignored him, but I felt a little uncomfortable. Will there be a problem?

Ignore him. A fortune teller once said that I looked like a man. I was very angry. If I looked like a man, there would be no women in the world. She just wants to cheat some money. How do they know our fate? They don't know how long they can live, and who is qualified to say that fate is in their own hands, not in their own mouths.
