rowuk, If you are so sure that this research has been done please direct us to it. I only know what my lung doctor told me and who am I to question his training and experience by asking for statistics? Concerning the Oboe, thatâ€™s my point exactlyâ€¦this type of wind instruments should only be played by the young players. I wish your daughter all the best in playing the Oboe. As to the Oboe players I have seen, I have seen a face thatâ€™s red with popping eyes and veins and so my eyes are relating this message to my ears. As to your other comments, I can understand one getting upset when faced with a problem that they had no idea about before. Itâ€™s like a person who has suffered a lack of sufficient blood to the brain most of their life and are use to being mildly retarded and get all upset when someone comes around and tells what may cause retardation. Rather then bury ones head in the sand, itâ€™s best to face it and deal with it. This is what internet has doneâ€¦.break peoples bubbles so that they can face reality. If it bothers you, you donâ€™t have to read it or consider it another plan to move forward. The choice is yours. Yes, whenever you feel blue, you should start breathing again for you might be suffering from VM.
