I am hoping some TCM students/practictioners can give me insight into this question. A little while ago on one of the other forums people were stating that they had been told that fingertip pushups, either regular or 'hindu' style, can lead to blindness/vision problems because they overstimulate the conglomeration of accupressure points located at the tips of the fingers. Can someone please tell me whether or not there is any truth to this?
