Death is an intrinsic part of life, and talking about the likely outcomes of illness, including death and dying, is an important part of health care. Doctors and patients vary in the language they use and in their comfort level regarding such discussions.
There are many benefits of exercise. Exercise is one of the most effective and, when done properly, safest ways to enhance health and wellness. For example, exercise can strengthen the cardiovascular system, lower blood pressure, improve the levels of fats, cholesterol, and sugar in the blood, strengthen muscles, prevent falls, and improve mood. As a result, people may function better, live longer, and avoid many common disorders. Benefits of exercise usually far exceed the possible harms.
Genes are segments of deoxyribonucleic acid (DNA) that contain the code for a specific protein that functions in one or more types of cells in the body or the code for functional ribonucleic acid (RNA) molecules. Chromosomes are structures within cells that contain a person's genes.
Traditional medical care focuses on improving health by identifying and treating health problems that have already produced symptoms or complications. In contrast, preventive medical care focuses on preventing health problems from occurring. Preventive care also focuses on diagnosing problems before symptoms or complications develop, when the chances of recovery are greatest. When done well, prevention improves overall health and reduces health care costs.
Rehabilitation services are needed by people who have lost the ability to function normally or have pain. Loss of function may be due to fracture, amputation, stroke or another neurologic disorder, traumatic brain injury, sports injury, and/or musculoskeletal impairments from conditions such as arthritis, spinal cord injury, heart or lung disorders, chronic pain, or being very weak (for example, after having some disorders and surgical procedures).
