Japan.. Hara Hachibo and 10,000 Steps and Ikigai

The Japanese diet is very similar to the Mediterranean diet, prioritizing seafood, fish, vegetables, fruits, seaweed and soy products, eating red meat rarely, and preferring chicken over this type of meat.

In fact, the Japanese diet "hara-hachi-bo" means a belly full of 80%, meaning that the Japanese stop eating before reaching the state of satiety by 20%.

This brings benefits to the health and financial situation as well.

Moreover, the Japanese are known for their popular love of hot baths and thermal springs, which drives them on vacations to go to balneological spas to improve their health.

Unlike many other countries, when they reach retirement age, Japanese people do not put an end to their career and can learn a new profession, do some volunteer work, join clubs and go to relevant places.

The Japanese idea of ​​"ikigai" - which is to give life meaning, color and taste - has conquered the whole world.

The youthful appearance of the Swedes is attributed to eating their chocolate as it contains polyphenols that prevent the development of heart diseases and cancer.

It is not excluded that the chocolate diet - or perhaps the standard of living in this country - plays a large role in the Swedish citizen's topping the list of "happy peoples", as revealed by the ratings of opinion polls conducted by various institutes.

According to these surveys, more than 3 quarters of Swiss feel happy and satisfied with life.

Koreans visit hot springs and baths with their families, colleagues or friends, believing that the saunas and springs maintain their youthful appearance until old age.

South Korea actively combats smoking, placing smoke-free signs at transit stations and near subway stations, cultural sites, restaurants and shopping malls.

Spain.. Naps, diets, buffoons and active retirees

"We work to live, we do not live to work" is one of the most popular proverbs in Spain.

In a related context, the Spanish diet is based on the Mediterranean diet, which includes greens, fish, seafood, fruits and vegetables, olive oil, nuts and legumes.

Experts say that following such a diet for 5 years significantly reduces the risk of developing cardiovascular diseases, diabetes, tumors and even allergies.

The Spaniards believe that the secret to the high life expectancy lies in the fruit of the jamun (a delicious black tropical fruit similar to a plum) which is rich in fatty acids similar to those found in olive oil.

In general, eating this fruit helps reduce cholesterol levels in the blood.

Spanish retirees also lead a dynamic life, visiting museums, going to cafés and attending a rock concert.

Residents of this country believe that all ages are suitable for learning foreign languages, playing musical instruments and practicing different types of sports, including extreme sports such as motorcycling.
