Reflect on the 5 stress reduction techniques we have done together in class.  Answer the following questions:

1. List 2 stress reduction techniques done in-class that you liked best. Explain why you liked these stress reduction techniques the best.

2. Based on your response to question # 1, have you used any of these techniques on your own time? If so, what were the results?  If not, which would you like to try and why?

3. Did you use any of the other stress reduction techniques (or any other technique that we did not employ in class; for example, acupuncture, massage, etc.)? If so, what were the results?  If not, what new/other technique would you like to try and why?

NOTE:  Separate the answers to each of your journal questions by beginning a new paragraph.  You should have 3 paragraphs.
