Yoga Anyone?

I've been asked over the years to try yoga in order to calm myself and help me think clearer.  I tried it several years back, but it didn't relieve my stress.  In fact, my body didn't improve at all.  I was getting sick every week.  I gave up that yoga class after attending it for several weeks. 

Tonight, I came across this article that says that yoga has been beneficial for autistic children.
