健康と心理学 1 Track 015 Health 子 Life Expectancy 80sec. 'Life expectancy is an estimate of the average number of years someone will live from their time of birth. Overall, life expectancy has been on an upward trend around the world. However, life expectancy is different when looking at 'sex, age, race, and location. The local environment can also 'have an effect on life 5 expectancy. In less developed countries, life expectancy at birth is lower 'compared to more developed countries. 10 To estimate life expectancy, researchers need 'reliable data. For example, they need to know the 'population, how many men and women there are, how rich or poor families are, among other things. Researchers also need to know data about the "death rate. Some countries have an efficient system to collect data, so it is easier to estimate the life expectancy of that country. 12 13 Things that can increase life expectancy in a country are sometimes very simple. Having access to clean water and having a clean bathroom is one way to increase the "duration of life. Another way to increase life expectancy in a country is to 15 expand its wealth. When a country is "affluent, it can "supply more hospitals and doctors, which then leads to better health 18 outcomes. This is one reason why developed countries have 2 higher life expectancies than less developed countries. 19 20. Humans around the world are achieving prolonged lifespans, but there are still inequalities between countries that we must work to overcome. (234 words)
