Flat living is becoming more and more popular in modern society, especially among young people who share flats with their flatmates. It offers many benefits, including the opportunity to socialize with others, save on rent and utilities, and reduce stress by reducing the burden of cleaning and cooking. However, it also brings some challenges, such as managing shared spaces and dealing with flatulence control devices in the kitchen.
