It is understood that this life happiness survey was mainly conducted through an online questionnaire. 2,371 white-collar women with an average age of 29 accepted the questionnaire. The survey content mainly involves a series of variables that may be related to life happiness, including the respondent's age, education, marital status, income, whether they have a fixed job, whether they have real estate, housing area, the income of people around them, and their opinions on material life. Attitude, whether you pay attention to face, etc.

The survey found that the factor that has the greatest relationship with life happiness is whether you own your own property, followed by whether you have a regular job. When investigating the life happiness of people with different housing areas, it was found that people with larger housing areas are happier than those with smaller housing areas. However, as the housing construction area exceeds 160 square meters, the happiness level decreases.

High-income people are indeed happier than low-income people, but as income increases, the relationship between the two gradually weakens. It is worth noting that relative income surpasses absolute income in the evaluation of life happiness. Relative income refers to the gap between one's own income and the income of peers. For example, a person who earns 3,000 yuan while those around him earns 2,500 yuan will be happier than a person who earns 3,500 yuan while those around him earn 4,000 yuan.

You feel most sexually happy if you have sex 8 times a month

Foreign studies believe that married people are often happier than unmarried people. Professor Xi verified this and found that people who were married within 5 years were the happiest, but those who were married for more than 5 years experienced a decline in happiness. In contrast, people who were unmarried and had no romantic partners were the least happy. In addition, through the investigation of the relationship between marital status and sexual life, it was found that sexual life has a greater impact on life happiness than marital status. Even after controlling for marital status, people who have more sex remain happier. But the happiness curve reaches its peak when having sex 8 times a month (twice a week). After more than 8 times, the life happiness curve declines.

However, Professor Xi added: This study can only measure the correlation between different variables, but cannot determine the causal relationship between them. For example, in the relationship between sex and happiness, survey data cannot determine whether more sex makes a person happier, or whether happier people have more sex.
