3D Glasses Anyone?

I examined and treated a man this week who said that he realized after doing deep breathing exercises that most of his adult life, he's seen things with a more 2 dimensional view than others. He stated that after deep breathing, things are more 3 dimensional. After determining that he had a Right Cortical Deficit, he was treated for the first time. He said that everything looked different, that he was seeing things as 3 dimensional again. I don't know exactly why that happened, but hurrah for his brain!   Dr. Merry
