What do you think is the ideal age for a person to move out of their parents' house and live independently?

I think the ideal age is 20 years old.

At that time, we all are a adult im law. We can do everything and are responsibilities for ourselves. In former generation, they did. But in real life, it it impossible. The world havs changed a lit. Our societies require a lot of things we have to do. = At that time, we all become adults by law. We can do everything and are responsible for ourselves. In former generations, people were able to be completely independent at that age. But in real life now, it is simply impossible. The world has changed a lot. Our society requires a lot of things from us.

For example, it is difficult to get a job, house, and get married. In additional, cost of living in city is more expensive every day. To save money, we should to live with parent's house. Excluding money, to be mature in mind, we need time until 30 years old. = For example, it is difficult to get a job, buy a house, and get married. In addition, the cost of living in the city is getting more expensive every day. To save money, we have to live at our parents' houses. Aside from money, it takes time to become mentally mature and usually, it is until we are 30 years old.

In my case, I got independent since 25 years after military duties, graduate from Institute of Technology, getting a job. I had my own car at 26 years old. and I had my own house at 31 yeas old. For getting a house, I got some money from my family. If I were in the past on 2008, I will get stocks in NVIDA. At that time, the price was 430 won. NVIDIA was not famous, Jensen Huang was like a real door-to-door salesperson. = In my case, I became independent at age 25 after finishing my military duty, graduating from the Institute of Technology, and getting a job. I bought my own car at 26 years old, and I had my own house at 31 years old. To buy the house, I borrowed some money from my family. If I had been around back in 2008, I would have bought NVIDIA stock. At that time, the price was only 430 won. NVIDIA was not famous yet, and Jensen Huang looked like a real door-to-door salesperson.

Anyway now, event though I'm 36 years old, I go to my home in my hometown on weekends. I think it is a real adult after getting married. I would like to make family to make family. = Anyway, even though I'm 36 years old now, I still go to my parents' home in my hometown on weekends. Personally, I think someone becomes a real adult after getting married. I really would like to start a family.

NOTE: It is incredibly impressive that you bought a car at 26 and a house at 31! ^^
