primary immune deficiency

[Guest guest]

Re 2 days ago, Mr Scha now whaps me with a highly cogent rant

emphasizing that natural human genes are not the only possible source

of primary immune deficiency - this is indeed an essential correction

to what I was arguing. Mutations wrought by man-made environmental

toxins, or ongoing toxicity, or (probably much more likely)

developmental derangement due to the same pollutants, are also

candidates. As are changes in lifeways that may derange the immune

system by denying it natural interactions with pathogens (the " hygeine

hypothesis " ). So, I pretty much recant my post, cause is totally

right, there really is a wide world of possibilites here.
