I did a test on myself(no drugs) I only read happy news for 2 weeks and I must say I feel great.
The news is filled with nothing but bad stuff just go to Google and click the news.Nothing but bad stuff.
Check out
http://www.happynews.com/ for one week and see if you don't feel better.
For the people who think i'm sticking my head in the sand I see no benefits to my life from reading about how some guy killed a bunch of people.
Simple fact is people have always killed and will always kill.
