I am much complimented and am willing to be of use wherever welcome so please rattle my cage appropriately but I protest that I am no medical man decidedly no epidemiologist and no virologist Also that I am a long way from the action just like the Texans Ummm Well putting it that way I ll go and browse a bit but in a bunfight in this scale I suspect it would be best if you directed me to points of major concern Cheers Jon
