Shallow breathing is like working a part-time job. You can't work part-time and expect to get full time benefits. It doesn't work that way. Plain and simple. If you want the benefits of full time work, then you must apply yourself accordingly.
Life is just like breathing.
Long, deep breaths, breath in the fullness of life. Short breaths, circumvent life. I would strongly suggest to anyone who is serious about living, and breathing fully, to take a yoga class, or rent a video on the subject. Every since I was a little girl, I had been curious about yoga, because I had seen this very skinny lady on television practicing it, every day. I too, wanted to be skinny, and be able to wrap my legs around the back of my neck.
