At one stage, both my wife and two teenage daughters were all diagnosed as having CFS (then referred to as ME, and earlier than that as "Tapanui Flu")
Their illness was genuine, too - my wife, in particular, would have dearly wished that she was merely faking it! As a consequence, I am less than kindly disposed towards those who hold that CFS is a bogus illness.
Around the same time as this was going on, it was estimated that at least 5% of the publishers in our circuit were afflicted with the same complaint.
Significantly, in the now 20 years since I broke with the JWs, I have not known even one person who is suffering from this illness. During the eighties, ME was often described as the "Yuppie disease." A better description might be the "Dubbie disease."
