Does Buddhism teach people how to solve the problem of survival?

Yes, it means that Buddhist scriptures are telling people how to live happier and better.

No, it means that the idea of longevity runs counter to Buddhism.

The Diamond Sutra says: Without me, no one has no life. This is the truth of the universe we live in. The idea of wanting to live a long life is just inconsistent with the lifeless Buddhists.

Many people have an incurable disease in the eyes of western medicine and are scared to death alive. There are still many people who completely put it down and then enjoy playing in places they have never played, or planting flowers and raising birds at home, or playing chess and cards with their neighbors. When the doctor thought they would die for three and a half months, nothing happened. Going to the hospital for examination startled the doctor, and the cancer cells completely disappeared. When asked about the treatment, they couldn't say it, just let go of their mood and play every day.

A good friend of mine was also sentenced to death twice by the doctor and given two critical notices. As a Buddhist, he is very liberal. Let's just say it's all fate As a result, he was alive, but the doctor who sentenced him to death died before him.

The answer to your question is: let nature take its course.
