The Shropshire primary school asthma survey: Spring 2005 was part of a project to further test a known correlation between examination performance and life expectancy.

This survey looked at the numbers of children in Years 3 to 6 together with the numbers of children in those years bringing inhalers to school for asthma.

[House dust mite "theory" has bitten the dust]

"the tendency to asthma may be completely cured by a slight change of locality, as, for example, by transference from the country to the town or from one town to another" [Black's Medical Dictionary, 18th Edition, 1944, page 76]

Dr van Steenis mapped out childhood asthma rates and proved huge variations, e.g. 38% of four to 5-year-olds were chronic asthmatic in downwind Whitland, Carmarthenshire, compared with just 1% in Aberaeron and other locations upwind of emissions from the oil refinery/power station complex at Milford Haven waterway.
