A person's cognitive level does not naturally improve with age; what truly matters is continuous learning, information input, and interaction with the outside world. If someone has long-term a lack of reading, few sources of new knowledge, and rarely participates in diverse social interactions, their cognitive structure is easily stuck at the original level, or even gradually hardens. However, this does not entirely depend on the environment itself, but more on whether the individual actively breaks through the boundaries of information. Through systematic reading, cross-disciplinary learning, and exposure to more diverse groups and more vibrant environments, a person can continuously correct their cognition, broaden their horizons, and achieve ongoing self-improvement.
