At what age should you start slowing down?

According to a 2024 study in *Neurology*, adults who had interrupted sleep in their 30s and 40s were more likely to show signs of cognitive decline a decade later, highlighting the importance of rest in midlife. This shows that rather than a specific age, the question of "At what age should you start slowing down?" depends on paying attention to your body's signals and adjusting your lifestyle for long-term health.
