SHOULD I SWITCH MY TOPIC OR DO I NEED TO STRETCH IT OUT.
No need to stretch anything out. Just find 7 or 8 great articles to read.
Find the main idea of each article and write a paragraph or two about it. A 5 page paper might have about 15 paragraphs.
Search the school library database for terms like this:
"freshman fifteen", weight, gain...
If you find good articles, just enjoy them and look for the main idea. Build your paper from those ideas.
