What are the actual roles of aged people in Asia,Africa and America?

This is such a broad question -- covering millions of people on three continents -- that a definitive answer isn't possible in this short space.

First we need to define what you mean by "aged people." How old must a person be to be considered "aged"?

If we consider "aged" to be over 65, we still have a huge variety of roles that they play in these three continents. I, along with many of my friends, are over 65, and many hold paying part time jobs, and volunteer for worthwhile causes. A large number of grandparents are raising their grandchildren.

The conventional wisdom says that the U.S. treats senior citizens as throw-aways -- but I think that has changed. American "aged" people live productive and independent lives and contribute to their communities. When they can't care for themselves, many are helped by family members while others live in assisted living or nursing homes.

Asian and African "aged" people have a variety of roles, depending upon their economic and family status. Most are also productive, although some may be taken care of by their families. Nursing homes and assisted living facilities aren't as prevalent in these regions.

To gather more specific information about the roles of aged people in Asia, Africa, and America, you could start by conducting research using reliable sources such as government reports, academic studies, and reputable news outlets.

Here are some steps you can follow to gather more information:

1. Define the age range: Determine the specific age range you are interested in when referring to "aged" people. This will help focus your research and give you a clearer understanding of the roles they may have.

2. Consult official demographic data: Look for official government reports or census data from each continent or specific countries within them. These sources often provide statistical information on the age demographics and may include information about employment rates, living arrangements, and social roles of older adults.

3. Research local cultural contexts: Consider the unique cultural contexts of each continent and the countries within them. Ageism, cultural traditions, and family dynamics can significantly influence the roles and treatment of older adults. Exploring this aspect can provide a more nuanced understanding of their roles.

4. Explore academic studies and research: Look for scholarly articles and studies on the topic of aging and the roles of older adults in each region. Academic journals focused on gerontology, sociology, or cultural studies may provide valuable insights. These sources often include in-depth analysis and case studies that can provide a comprehensive understanding of the topic.

5. Seek firsthand accounts and personal stories: Look for personal accounts, interviews, or documentaries that offer firsthand perspectives from older adults themselves. These narratives can provide unique insights into their lived experiences, challenges, and roles within their communities.

Remember, due to the immense diversity within each continent and country, there will be variations in the roles and treatment of older adults. It is important to approach the topic with an open mind and consider multiple perspectives.
