Joe, Microbes—they may outlive us as a species, but not individually. Well, nowadays I always know that I am overseas, certainly visually but also olfactory [and I do not mean the cooking]. Werner -----Original Message----- From: Joe Fjelstad <[log in to unmask]> To: [log in to unmask] Sent: Tue, 28 Apr 2009 11:48 am Subject: Re: [TN] Hand Sanitizer and PCB Assembly I don't know Brian, we all often smelled pretty rank in Vietnam (though some were worse than others) so the monsoons were a treat. That said I am reminded of a reported anecdote of Ben Franklin in France when some lady said to him "Mr. Franklin, you smell" to which he replied "No madam, I stink, you smell" But I do agree that microbes have an important role to play. We cannot kill them all and they will long outlast us. Joe In a message dated 4/28/2009 8:06:56 A.M.

If your immune system is not trained to the local strains of E. coli or salmonella, when you come in contact with a few bacteria on the salad in a chic restaurant or elsewhere, you will get the full benefit of a day or two enthroned. Merde alors! You must have exposure to bugs to be healthy. I remember reading about an experiment during the Viet Nam war. A non-combatant unit was split into two equal groups of volunteers, one of which could shower as often as they liked, minimum daily, the other half could shower once every third day. The troops had to report every health abnormality, even minor, as well as those on sick parade. The "dirty" lot reported far fewer bo-bos and serious problems than the "clean" lot (can't remember the statistics, but they were quite significant). After a few weeks, the "dirty" lot no longer exhibited undue BO, either, showing that the skin flora causing fermentation in/around the sweat glands do not have a chance to be eliminated naturally with frequent washing. This was confirmed in the UK army: some units in hot climates had shower facilities once a week and BO was not a general problem (there were a few odd bods who were smelly from "nervous sweat", as opposed to honest-to-goodness hard labour sweat). I think there is probably an optimum balance which may vary between individuals, but there is a tendency to go OTT with personal hygiene.
