Why is it said that "harmony in the family is the key to happiness"?

I believe that when people reach old age, the main thing is to achieve harmony between the spiritual and physical sides in order to be happy. In general, there are the following aspects:

I. Health

The body is the biggest capital

If the body is healthy, people are old, and do not need to be served. And legs and feet, where you want to go, do not need to trouble others. The quality of life, do not give the children trouble. It doesn't matter if you're rich or poor, it's your health that counts.

II. The couple loves each other.

One of the closest people in the old age is of course one's own partner, who can know the cold and warmth, and knows best about one's own life and work habits, and takes care of each other. If you have a companion in your old age, you will not be lonely, and you will be able to talk to each other about your pain and suffering, and you will be able to live with them for the rest of your life, which is a blessing.

Three. Children filial piety, family harmony.

People in old age, if the children and grandchildren know respect for the elderly, filial piety, large families, small families have harmonious relations, have a happy family, this time no worries, good mood, good spirit, feel the most happy.

Four. Do what you like, spend every day happily.

People old, generally have to have some hobbies, the days are full, you can plant flowers and grass, dancing, take time out to exercise a little more physical, living in a full, happy mood, able to prolong life, the happiness index naturally rise.
