Please watch the following video and answer the question below.  How to live to be 100+ by Dan Buettner How to live to be 100+ – Dan BuettnerLinks to an external site. The lifespan of adults in the United States has increased substantially since the early 1900s. The average lifespan in 1900 was 48 years whereas the average lifespan in 2020 was 78.8 years. However, within the US, there are substantial differences in life expectancy based on demographic factors such as sex, race or ethnicity, socioeconomic status, location where one lives, etc. Moreover, the US currently ranks 28th out of 37 for life expectancy among similar economically developed countries. That is, we are in the bottom 10 for life expectancy when compared to other economically developed countries (https://www.americashealthrankings.org/learn/reports/2020-annual-report/international-comparisonLinks to an external site.). Based on the textbook readings, the information provided in the video above and external resources as appropriate, explain why (a) life expectancy has increased in the US and (b) why life expectancy in the US is lower compared to other countries. In your response, consider (1) what factors contribute to older adults living a long, healthy life, (2) what factors contribute to a shorter lifespan or life expectancy and and (3) factors or areas the US would need to improve upon to improve life expectancy and catch up to other countries.  You must post an initial reply post by ,3/15 Your initial reply post must meet the definition of substantive.
