Warning! Rant ahead! Ouch! 2,4,5 T (agent orange) has a bad rep! You dodged the bullet. Statistics of ones are a bitch! When young one does all sorts of jobs. HS picked fruit, awful job. For 4 summers I was a forest service fire lookout; isolated lonely but financed a degree. Got drafted when the Berlin Wall went up; assigned to Dugway Proving Ground as a 939.30. Did plague survey and then worked on a way to use chemicals detectable at low levels to quantitate distribution of aerosol sprayed on a large grid, think nerve gas, etc. Moved back to Pullman and did c14 and H3 dating. C14 for archeological sites and deep aquifers and H3 for shallow wells. When carbon dating went slack for a month I got loaned to Polymer Chemistry to do a Mol Wt determination on straiten ( a long-chain polysaccharide extract from larch. Next was a job as a chemist/microbiologist for Wa Dept of Agriculture checking to see if ag products met label guarantee on feed and fertilizer. Protein, fat, and fiber on feeds and N,P,K on fertilizer. Various drugs and antibiotics in feed, microscopic analysis of feed and fertilizer for specific contents and adulteration. Being lazy I managed to sneak a pdp11 into the lab by saying what it would do not what it was. We replaced readout on the Perkin-Elmer AA with the 11 and 12 bit A/D. I did the electronics and one of my chemists did the software. It did the job until we replaced it with a new AA that still didn’t have the capabilities of our custom system but was off the shelf. I never did get the lab system up to the point where I could report results directly off the database. Administrators tend to get paid by how many people they supervise not by what the do so there Is no incentive to be efficient. Retired the first day I could. Good decision!
