According to various sources, the average age of death worldwide is around 72-75 years for both sexes combined. However, this varies greatly by country and region, depending on factors such as income, health care, education, environment, lifestyle, etc.

There are many ways to reduce the number of deaths and increase the average age of people. Some of them are:

   - Improving access to quality health care and preventive services
   - Reducing poverty and inequality
   - Promoting healthy behaviors such as physical activity, nutrition, hygiene, etc.
   - Preventing and treating infectious diseases such as COVID-19, malaria, tuberculosis, etc.
   - Addressing environmental issues such as air pollution, climate change, water scarcity, etc.
   - Supporting mental health and well-being
   - Enhancing social support and community engagement

These are some general suggestions that may not apply to every situation or context. The best way to improve this situation is to identify the specific causes and challenges that affect different populations and regions and tailor solutions accordingly. This may require collaboration among governments, organizations, communities and individuals.
