The fortune teller said that my grandfather would live to ninety-nine after he was seventy-nine.

This compliment is very popular. The old man can live to be 99, and the whole family is very happy. Consider it a blessing. In fact, fortune tellers always say how old you can live after the hurdle, what great career you can achieve after the hurdle, and so on. Generally speaking, they will calculate that you are either sick or have a major setback in your work and career.
