Did you have fun playing with your calculator while I was out of town?
While you were amusing yourself and trying to demonstrate your superiority, it appears that you missed the major points of this thread beginning with the initial one - experts have warned that fully 10,000 chemicals need to be tested for safety. The article did not suggest that every possible combination be tested, nor did subsequent posts suggest that it was feasible to do so, only that we are basically operating in the dark because of the effects of such combinations not being known.
But again, the point was that the 10,000 chemicals according to the original post DO need to be tested, and I would add that it certainly it would be feasible to test at least the most common combinations of industrial chemicals as well as the most common combinations of prescribed and over the counter medications, and well worth the considerable time and effort for the sake of humanity. Of course it is quite unlikely to ever happen because of the ever so simple equation of profits versus humanity - an equation whose outcome has ever held true in industry and in medicine.
The other posts, including your own amazing demonstrations in inanity, combine to make the second, and most important point of all (perhaps you missed it while gloating or while seeing how far you could calculate "pi"), is just how far man has gone in poisoning ourselves and our planet.
Far beyond the point of no return it would appear.
