Good and stable health helps people of all ages surmount life’s challenges, excel in school and on the job, ensure their families’ well-being, and fully participate in their communities. Safe neighborhoods with low levels of environmental contaminants reduce people’s risk of health complications that may undermine school or work performance. High-quality and accessible health services can help parents get their children needed care through critical formative years and enable adults to obtain tests that screen for early detection of diseases, which can reduce long-term health care costs and give people power and autonomy over their lives.
