Is Google trying to tell me something?

Topic: Google AdSense

I just tried this tool to see what ads Google's AdSense would put on this page, and it came up with these:

Stress Management
Stress Management
Stress Management Pill
Relax, Soothe, and Relieve
Secrets to Reduce Stress

Hmmm. I don't think I'm all that stressed out. And the word "stressful" appears only once on this page, and "stress" not at all.
