Pat, I don't know what is causing your problems, but when asthma and PD decide to see which one can cause the most problems witth me, I just reach over and put on my "blue glasses" and within seconds life is back under control. It is a known fact that the color blue is an antianxiety color. It has a calming effect. If I didn't have the blue glasses I would most likely be at the ER. The last time I went to the ER I had a staff(sp) infection. They treated my asthma with four treatments plus an X-ray. The infection was ignored. The cost was $1,600. That is what they tried to charge my insurance company. Blue glasses sure are alot less expensive. Regards, Alan Bonander [log in to unmask] San Francisco Bay Area
