I can't resist posting about this.
In the June edition of Hoard's Dairyman, the National Dairy Farm Magazine, there is a little blurb about the benefits of manure in the Farm Flashes section.
Here is the basic gist of it:
DAIRY FARMERS FIVE TIMES LESS LIKELY TO GET LUNG CANCER
The bacteria in manure is preventing lung cancer in dairy farmers. In a study of 1,561 Italian dairy farmers they were 5 times less likely to get lung cancer than their local counterparts, as reported in the Journal of Indoor and Built Environment.
Active dairy farmers breathe in a lot of dust and when working around their cattle that dust includes dried manure along with the bacteria that grow in it. The endotoxins in the bacteria build up immunity in the body which in turn reduces the risk of developing lung cancer, reported researchers from the University of Padua in Italy. The greater number of cows, the greater the protection for the herd owner. Dairy manure even helped dairy farmers who smoked; they were less often diagnosed with lung cancer than other other smokers.
If you wish to reduce your chances of developing lung cancer, whether you smoke or not, just mail me a donation (I will leave it to your perspicacity to determine the amount) and a few bucks to cover the cost of postage and I will send you a quart ziplock freezer bag of dried cow puckey you can pulverize and sniff off and on all day.
