Why do the Americas, Europe & Western Pacific Asian countries have higher life expectancies that Africa, Middle East & SE Asia?

The Americas, Europe, and Western Pacific Asian countries have higher life expectancies than Africa, the Middle East, and Southeast Asia because the living conditions in them are much better.

Explanation:

There are differences in life expectancy among people from different countries. In some cases, the differences are small, in some medium, while in some cases the difference in life expectancy is a whole two times. There are numerous reasons for this, but in general, it is the development level of a country or a region that determines the life expectancy of the population in it.

The most developed countries where the living conditions are the best are found in the Americas, Europe, and Western Pacific Asian countries. The standard of living is high, the food abundant and diverse, people can afford many more things, health care is on high level, etc. On the other hand, the regions like Africa, the Middle East, and Southeast Asia, have poor living conditions. The people often lack clean water and food, the health care system is bad, the living standard is very low. All of this contributes to people to have much shorter lives than the people in developed countries.
