They are portrayed as heroes and as being better than "Average" people. They are portrayed as super fit and that people should be like them. This portrayal causes people to feel less about themselves and to have fitness/weight goals that may be unrealistic or impossible for some.

To write an essay about a historical event, I would do research. I would consult textbooks, the internet, and other resources that have information relevant to a historical event that I am writing an essay on. To write an informative essay about a historical event, I would want a strong thesis statement, and strong supporting body paragraphs. I would want the body of my essay to be full of detail and factual information from my research (which of course you want to sight :)) Additionally, I would want to use strong transition words and powerful vocabulary. Finally, I would want my essay to be engaging.
Hope this helps :)
