Is fortune telling accurate? The fortune-teller said that my sister's grandmother would die in a few years, and then her grandmother went to the hospital for a checkup.

There is no basis. The fortune teller himself doesn't know why. The main reason is that it is not credible. And all the fortune-telling words are extremely inaccurate and the scope is not detailed. These results can be predicted by conventional thinking. If the old man is sick and old, he will surely die easily. Taking care of yourself actively is the right way. When you say you will die, does that mean giving up?
