For example, you’re cleaning a room, your home or your apartment. And you find it defeating the purpose to dust things and wipe them down because, dust comes back anyways and eventually. It might not be as bad as it was or as bad as it could be, but you’ll always end up with dust and cleaning dust is just a grand waste of effort and time.
The purpose is allergies and a night’s sleep without coughing and sneezing. If you don’t have sinus problems before, you may develop them later in life from excessive exposure to dirt and dust.
