Thanks for this, Wayne. I had that site bkmkd long ago and may even have that article saved on an old CD.
I found out about 2 yrs ago that Joe Viallis had died, though I did not learn the cause. He had a very interesting website that was mostly politically oriented. I'm glad to ensure I have the Potassium article again. Sharon I forgot .......... the file name is potassium_01.doc http://www.fugitt.com/files/
