One: I work long hours, but I can have food and shelter. Older people who are generally willing to be security guards may be in poor health or have too many skills, but the company provides food and accommodation, so they prefer to stay in this place because it can really save them a lot of money.
Two: Old people don't have many friends, but the profession of security can communicate with people. I've seen a lot of security guards. He is not short of money, but he just likes doing this job. He is more comfortable in this profession and won't have too many troubles. He just sits there and communicates with others. Although the job of security guard is not respected by others, he loves it himself. He thinks he can create value when he is old. ?
Three: It may be because of family that we can be closer to our family. Many parents choose to work near their children. For example, his children work in a school, and he wants to find a job as a school security guard who works here. He feels that he can be close to his children without too much sense of distance. At the same time, he can give them some care, sometimes help them, and at the same time get a salary, which will not cause too much pressure on children and reduce their burden.
