Most people born in the 80s have their own families and stable careers.
Post-80s people who are between 30 and 40 years old are in the most difficult stage of their lives; they need to face the problem of having children after marriage, and they also have the responsibility of taking care of two families, and they also have to work hard, and their parents start to grow old and their children start to grow up, and the pressure of work and family piles up at once.
The rising standard of living is also forcing them to work harder, and the children's parents need to be taken care of as well.
