Research Paper on why the drinking age should stay at 21; Thesis Statement help

I'm writing a research paper on why the drinking age should remain at 21. Its 3-5 pages, so far for my thesis statement I have: Keeping the Drinking Age will help prevent tragedies, decrease car accidents, and keep people safer.

What are some ways that I could make this better?
