so serendipitous - the other day ago I was putting down some wood flooring in my house and hurt my back a little - something that happens from time to time in exactly the same place - so I knew that I should get on top of it and take a couple of ibuprofen.

So I take a the ibuprofen, and take a break for an a couple hours - and as I noticed the back pain go away - I also noticed a distinct improvement in my mood! I had the exact reaction described in the article "of course, your back doesn't hurt ..duh".

The article makes me wonder if there is another explanation for the mood improvement ..
