Someone of my acquaintance, a forty-six year old female with severe chronic asthma has been attending Kung-Fu classes for two plus years. When pushing herself to the point of obtaining her "second wind", she has trouble the following day at work. She has trouble with concentration and focus and makes numerous mistakes of which she is unaware, until they are discovered by someone else much later. She would like to train more seriously in order to obtain an acceptable degree of excellence in Kung-Fu, but she feels that she cannot until this is resolved. Does anyone have any suggestions how to fix this problem or to what might be causing it.

Very some such,perhaps might have been, likely say some, some not.
