Research retirement in the United States

In at least 1,000 words (excluding title page, abstract (optional) and reference page), research retirement in the United States. In your paper discuss the retirement age of 65. Where did this age come from? Does this age still work? Are more people working past the age of 65? Is retirement as stress free as it is portrayed in the media or is it dependent on other factors such as financial security, capacity, etc.?
