People's lives are short and long. Although each of us can't extend the length of life, we can expand the width of life. Living every day well is the greatest meaning of life.

How to live longer?

1, female life expectancy increased 10 years.

Women in almost any country live longer than men, with an average life expectancy of about 10%. In addition to environmental and genetic factors, the short life span of men is also related to androgen, which determines men's aggressive and competitive behavior, making them more prone to premature death caused by violence, accidents and adventures. Androgen also lowers the cholesterol level beneficial to the heart, while estrogen in women increases the cholesterol level beneficial to the heart.

2. Happiness usually increases life expectancy by 9 years.

The study found that people with optimistic attitudes have a healthier lifestyle, and they spend more time in sports and social activities. Optimists recover faster from illness and trauma, live longer and are less likely to be disabled. Happiness can increase the number of disease-resistant and antibacterial cells, thus improving people's immunity.

3. Life expectancy after marriage is increased by 7 years.

Compared with divorcees, widowers, widows and bachelors, married people live longer. A study in the United States found that people who have never been married are 2/3 more likely to die prematurely and are more likely to encounter economic crisis and physical and mental health problems. Once a disease occurs, married people will recover faster, and the survival rate will be higher in the face of some cancers.

What do you eat to live longer?

1, auricularia auricula

Auricularia auricula contains 98 mg of iron per100g, which is about 5 times higher than that of pig liver with the highest iron content in animal food and 30 times higher than that of spinach with the highest iron content in green leafy vegetables. Without iron, we have no fresh blood, and fresh blood is an important part of hemoglobin. If iron is deficient, it will lead to weakness, irritability, forgetfulness, pallor, dizziness and palpitation.

2. apples.

Eating an apple a day can greatly reduce the risk of Alzheimer's disease. Quercetin contained in apples not only has anti-inflammatory effect, but also can prevent the development of cancer cells. Apples are also rich in vitamins and minerals, which can improve human immunity and cardiovascular function.

3. cheese.

40 g cheese =200 ml yogurt =250 ml milk. A small piece of cheese contains as much calcium as a large glass of milk! Calcium is the most abundant mineral in the body, and 99% of calcium exists in bones and teeth to build a powerful "hardware" of the body.

4. pears.

Pear is called "natural mineral water" because it is fresh and juicy, contains 85% water, is sweet and sour, and is rich in vitamins and trace elements such as calcium, phosphorus, iron and iodine. Since ancient times, it has been known as the "Hundred Fruits School".

5. buckwheat.

Buckwheat contains powerful antioxidants, which can reduce blood lipid, enhance blood vessel elasticity and prevent blood coagulation. It is a good heart-protecting food. In addition, it also has a good effect of lowering blood pressure and helping sleep.

6. fish.

People who care about heart health should eat more fish, cook fish dishes three times a week or eat 30 grams of fish every day, which can reduce the risk of stroke by 50%. Medical research has proved that Japanese and Eskimos who often eat fish suffer from cardiovascular diseases in a much smaller proportion than those who seldom eat fish.
