Rivet,you might want to check out SYBD. Soon starting part 3 of the first phase of clinical trials. Synthetic blood showing promising results. Seems to have support at .40, yet there is a gap in the .20's. Real interesting experiments done with this. Remember ever seeing a picture of a mouse living in a fluid? That fluid is now being tested as a replacement for blood. By the way, nice house you got here. Regards, Trigg
