Is 99 the deadline?

The age limit is not fixed, but varies from person to person. Everyone's life span is affected by many factors, including heredity, lifestyle and environmental factors. Although 99 years old is quite old, it does not mean that it must be a deadline.

There are many people around the world who live to be over 100 years old. Their examples prove that age is not the key factor that ultimately determines life span. Especially with the development of modern medicine, people pay more attention to health management and medical care, which also helps to prolong life.

Even so, I still can't give a clear answer, because everyone's life span is uncertain. We should pay more attention to how to keep healthy and improve the quality of life, instead of worrying too much about age.
