Nmw - I wasn't being hostile - I wasn't even upset. I was stating something matter-of-factly. I am sorry Purusha if you thought I was being mean. I was being sarcastic so I am sorry for that. I was just going to tell you when I saw that Nmw posted - but I was going to tell you if you strongly believe in something like this - why don't you present it to the Cystic Fibrosis Foundation in a manner that they might consider doing research maybe on the lungs of rats. You never know that if it is really tried maybe it is a possibility. I would not want it to be tried on a person though until we know what the result is. The CFF has a lot of money now and hopefully they are trying everything possible to save every life that has CF with every kind of bacteria. I was only being sarcastic, not really meaning anything against you Purusha. I welcome your new ideas as anything is a possibility.
