One truth is simple : CULTURE and DISCIPLINE

Japanese have this kind of character that makes them live long. You can see how beautiful, clean, fresh and organized Japan is because they've build a character that helps them grow - even older. As I've watched a video from Nas Daily, an average of 80+ year is their normal life span. Because of a couple of reasons :

- Food - They've developed cuisines and appetite that makes them consume food that provides a lot of good nutrients. From their Sushi, to eating nutritious diet and to eating sustainable amount of food that they need.

- Culture - They have a culture that makes them live happily and have the time to meditate. 

- Homes - They have built homes for simplicity, appreciating things in their surroundings. They have homes that makes you not stress. When you wake up, you will be faced with sunshine. 

- Lastly, Technology - Japan has the best technology around the world and the people are using it. Their advancement of technology is shared among the people, making their life convenient and self sustaining.
