Health refers to a state of physical, mental, and social well-being, where an individual is free from illness, injury, and disease. It is a dynamic and multifaceted concept that involves various factors such as genetics, lifestyle, environment, and access to healthcare. Maintaining good health requires a balance of physical activity, healthy eating habits, adequate rest, and regular medical checkups. Poor health can have a negative impact on a person's quality of life, ability to work and earn a living, and overall well-being.
