What contributes to higher life expectancy in developed countries?

• A. Warmer climate
• B. Nutritious food and good healthcare systems
• C. Higher birth rates
• D. More entertainment options

Answer: (B)

Access to nutritious food and strong healthcare systems is what pushes life expectancy higher in developed countries. Nutritious food supports healthy growth and immune function, while robust healthcare provides vaccinations, disease prevention, early diagnosis, and effective treatment for illnesses and chronic conditions. Public health infrastructure—clean water, sanitation, safe housing, and disease control—further reduces deaths from preventable causes. Higher incomes and education in developed nations enable healthier lifestyles and better access to medical care. Warmer climate by itself isn’t the main driver of longevity, and higher birth rates or more entertainment options don’t directly increase how long people live.
