Why are you optimistic? We must first understand the advantages and disadvantages of brotherly love and its causes.
Advantages of sibling love: 1 In terms of life expectancy, women usually live longer than men (in the street, it is usually to watch grandma help grandpa walk, not grandpa help grandma). Two people have been together for most of their lives, and no one can live without their old age. The older a woman is, the shorter the separation time will be. Second, physiologically speaking, women's sexual development is earlier and lasts longer, while men's development is slower. Women mature at the age of 17- 18 and last until 50-60 years old, while men mature at the age of 18- 19 and last until 40-50 years old. Women are 3-7 years older than men and are the best sexual partners. Third, in terms of personal growth, girls mature earlier than boys both psychologically and physically. Girls are older and more mature than boys, so they can take better care of boys. When encountering problems, they will not solve them by "doing", but can communicate and negotiate with the other half, which will make the family more harmonious.
What are the disadvantages of sibling love? First, the love between brothers and sisters is not valued by others. Because since ancient times, men and women have basically married men and women, which is a natural tradition. If it's a sister-in-law relationship, it's a break from convention and is generally not favored. Second, men are anti-aging and women are not. Ergonomically speaking, men generally age slower than women, that is, women age faster. If women are older than men, once they reach middle age, their looks will not match those of men.
The reason why there are more and more brotherly relationships: In general, it is because the divorce rate in China is getting higher and higher. When parents divorce, boys may lack maternal love and sense of security, so they hope to find a girl older than themselves, because older girls are more mature, can take care of themselves and find a sense of security. Psychologically speaking, in many people's subconscious, they are looking for maternal love all their lives, whether because of the lack of childhood, seeking compensation, or because of the beauty of childhood. The more successful a man is in his career, the more he yearns for the initial warmth and security in the world when he takes off his armor, which provides psychological soil for brother-sister love.
So I am more optimistic about the love between brothers and sisters. Although there are some minor shortcomings, there are still many advantages.
