Decreased quality of life is largely attributable to 3 categories of health issues:
- Musculoskeletal problems
- Cognitive problems
- Mental health/relationship problems
Why it matters:
Just like the main causes of death (cardiovascular disease, cancer, dementia), the main causes of human suffering can largely be prevented or at least delayed with attention to healthy behaviors. Additionally, effective treatments for such conditions are known, and often include exercise, sleep, or nutritional approaches.
(Of course, there are many illnesses and conditions that fall outside these categories, but for now let's focus on a few basic principles that can help to keep us on the high end of quality of life.)
