Improving quality of life is an important goal that encompasses many different aspects of health, including physical health, mental health, and social well-being. This progress not only increases self-confidence and happiness but also plays an important role in closing the health gap that exists between different societies. Health inequality refers to inequality and resistance to changes in health due to factors such as economy, location, and access to health care. By addressing this injustice, we can create a healthier society in which all people can thrive.
