Why do people in these countries live so long? Scientists believe it's not a single secret, but a combination of several factors: high-quality healthcare, a healthy diet, a high standard of living, regular physical activity, low smoking rates, and good disease prevention. For example, in Japan and Hong Kong, people traditionally eat more fish, vegetables, and seafood, and also walk a lot.

It's important to understand that a high average life expectancy doesn't necessarily mean everyone will live to 85 - 90 years. This is a statistical indicator influenced by lifestyle, heredity, the environment, and access to healthcare.

The main conclusion is simple: the country of residence plays a significant role, but our daily habits are no less important. A healthy diet, physical activity, adequate sleep, and regular medical checkups can significantly increase the chances of living a long and healthy life.
