Altman came up with a good report IMHO.   Timely too.

Given the limits on staff and the technologies then available, Altman's
one-off report borders on little short of amazing.   Altman got the
numbers right, and by so doing, broke through the foggy
notions, then existing, on CS toxicity, bio-accumulation, and dosage;
and, thereby established a solid foundation for the future growth of CS.
Some of his assumptions were wrong, but his tables were flat right.

We now know that the body flushes out ionic silver as soon as possible,
and uses the silver nanoparticles to battle the pathogens in our
bodies.  Long
story short, excess CS exits via the urine, while beat-up nanoparticles
exit the body via liver, bile, feces route.   Hence, the need for regular
replacement.

Hat tip to Roger Altman.
