For Pinkfreud:
Most persons, at any rate those who live in colder climates, have
heard claims that weather conditions can aggravate ailments. The
typical one familiar to me is that cold, damp weather causes arthritic
joint pains to worsen. Some sufferers move to hot, dry desert climates
seeking relief.
    Now, I am not belittling  or discounting such beliefs, but I ask:
Is there any proven, scientific validity to this belief?  The human
body, although  not a secure, closed environment, is certainly well
protected against many physical aberrations. Our bodies are stable, 
temperature controlled aqueous mechanisms. How could  relatively
slight temperature or humidity weather changes cause severe
discomfort, especially with those fortunate to live in heated
comfortable dwellings?
