It seems that living in our sanitised and sterile Nanny cocoon is in fact rather bad for us.
There has, over the past 30 years or so, been a steady rise in the number of people claiming that they are allergic to all manner of things, from housemites to nuts.
Needless to say some of these claims are in fact hysterical BS, caused by the modern cultural fad for looking for reasons to excuse laziness, idleness, bad parenting and fussiness with food.
However, there has also been a rise in the number of people with genuine allergies.
Epidemiologists are theorising that the benefits of modern life, such as mains water supply, improved drainage and the greater cleanliness that is now de rigeur has caused us to become weaker when it comes to our responses to outside stimuli such as mites, animals, dust and nuts.
In Eastern Europe people continue to live in close proximity to animals, as such the incidence of the common forms of allergy remain low.
It seems we have become far too clean.
The irony being that the one area which should be 100% spotless, namely hospitals, Nanny has allowed to become absolutely filthy.
Funny that, isn't it?
Anyhoo, the lesson is clear; let's get dirty!
