David is watching this science show on dark matter, and I couldn’t help but see certain things in common with our immune deficiency–our immune system deficiency is something that has an impact on our immune system, but we can’t see it or label it, but we know for a fact that it is there (by things like the absence of a fever and elevated wcb when there should be one–)

Obviously, what’s wrong isn’t dark matter, but I think it’s something like that–

I think that’s why the IVIG is helping more than we can ‘prove’. It’s solving a broken piece that we can’t even measure yet.
