The Japanese are the absolute champions in longevity, due to healthy diet and top quality healthcare system.

According to data from the World Health Organization, the nations with the highest life expectancies are:

• Japan: 84.3 years
• Switzerland: 84.1 years
• Singapore: 84.0 years
• Spain: 83.5 years
• Italy: 83.4 years

There are several factors that contribute to longer life expectancies in these countries. One factor is access to high-quality healthcare, including preventive care and treatment for chronic diseases. These countries also tend to have strong public health systems, which can help to prevent the spread of infectious diseases and promote healthy behaviors.

Other factors that may contribute to longer life expectancies include a stable political and social environment, a high standard of living, and a healthy diet. In many of the countries with the highest life expectancies, people tend to eat diets that are rich in fruits, vegetables, and other healthy foods, and they engage in regular physical activity. Additionally, these countries tend to have low rates of smoking and alcohol consumption, which can have negative impacts on health.
