Thesis statement for "Stress Effects on Health and Behavior" and what are three major points?

Someone could certainly give you a thesis statement and 3
topics for this paper - but then the paper wouldn't really be YOURS.  You need to own
it.  The best way to do this is to draw these things from what you already
know.

An easy way to come up with a thesis statement (and
material for an entire paper, really) is to follow these steps
first:

1. State the topic in the form of a
   question.  What are the effects of stress on health and
   behavior?


2. Brainstorm a list of 15 - 20 answers
   for the topic question.  Be as general or specific here as possible - remember
   it is just brainstorming so no ideas should be ruled out.  Also, keep in mind both
   negative and positive effects of
   stress.
   


3. Categorize answers into
   three logical groups.  Do not make two of your categories the "negative"
   effects and the "positive" effects.  Instead, focus on one or the other.  Otherwise your
   final paper risks a lack of
   cohesiveness.


4. Write thesis statement by giving
   a general and complete sentence answer to the topic sentence.  While stress
   has both positive and negative effects on health and behavior, the negative tend to
   outweigh the positive.

Then, your
next sentence is blends naturally into identifying your three categories (major
points).  Hope this helps.
