I was never in the military at all, but came very close to being drafted and sent to Vietnam with an inferior rifle, the Colt M-16, and had President Nixon not ended the draft in 1973, the year I graduated from high school I was not drafted, but I still had to register with Selective Service. I went on to junior college to become an auto-tech or "mechanic", specializing in repairing all the newer vehicles with air-conditioning systems and to lesser degree the automotive emission control systems, but I've rebuilt engines, clutches, transmissions and overhauled the many of the carburetors of the time as well as many other automotive devices and car or truck parts, saving lots of money for my family, and for myself, even now. I do all my oil changes, spark plugs or whatever I can still manage to accomplish at my age.
BTW, speaking of being in the military, anyone who lies about that should be sent to a prison. I've nothing but disgust for anyone who lies about that. I had a so-called "friend" in my youth who lied about fighting in Nam', usually to young women, to impress them. He graduated high-school in 1974. He lost a very intelligent and very nice girl-friend to that lying. He also lost me as a friend. You don't lie about such things around me, period, without consequences.
Thankfully, we have much better vehicles that use fuel injected engines, with the 1986 Ford coming out with a full fuel injection system before Chrysler and Chevrolet did, allowing for the high compression motors of the 1960's and early 1970's to return to the roadways, with much more power the 1973 to 1985 motors, which used low compression engines that were quite low-powered. A 1977 Pontiac Grad-Am as seen in the film industry, such as in "Smokey and the Bandit", were low-powered and only appeared to be fast. My own car would and could have SMOKED Burt Reynolds, easy.
We also got rid of leaded gasoline's in 1974-75, and the children of this world no longer need to have their IQ's reduced due to this toxic chemical absorbed into the lungs from exhaust fumes, and if spilled, the skin, r eaten in old house paints. It was developed as a substitute for Ethanol during the Prohibition of Alcohol from the "roaring 20's when Ethanol was banned for 13 long years. People back then knew about "Jury Nullification" so the law was judged, and the case dismissed. Nowadays, all judges, who are also attorneys, inform the jurors, that they must follow the charges leveled at the defendant, even if the law is unjust or unconstitutional. They never think ahead to the fact that one day they might become a defendant in a court of law themselves, and everyone seems to wish to charge the defendant as being guilty more times then not.
Being on jury duty is in no way fun, but it is your duty to show up and listen carefully to all the evidence. You _CAN_ still nullify the law and allow him or her to walk free, as in the O.J. Simpson case, where the cold-blooded killer of two innocent people, man and a woman, was allowed to walk out of court as free man. The jury seemed to ignore the DNA evidence against Mr. Simoson entirely, and the judge allowed it.
But back to the issue of leaded gasoine, It increased the compression of newer, more powerful engines so that they did not have pre-ignition, or "Knock", but all Lead is toxic to most all life-forms, and only the mercury amalgam in teeth filled with so -called "silver" fillings, with 50 percent being mercury, but not called that by the ADA, and banned in several countries in Europe, and I believe Canada has banned it as well, recently and is even more toxic then Lead. Tuna has lots of mercury, as it was used to mine Gold and Silver in the 19th century, and flowed into the oceans of Earth. Many mountain streams are still contaminated with Mercury, not safe to drink at all. Automotively speaking, now that Lead has been banned in all gasoline and most all non-commercial paints, many motor vehicles can run spark-plugs out to 100,000 miles and 5000-to 7500 miles on a change of Synthetic lubricants, not 3000 miles on oil and filter and 5000 miles on a spark-plug and ignition points. Electronic Ignition was in existence since the early 1970's, and I had changed my father's 1960's gasoline truck and pickup engines over to E-I, saving fuel, with no more monthly ignition points changes, and also installed a more efficient Holley Carburetor with a vacuum-advance system, increasing power and gasoline mileage, while decreasing emmisions and less spark plug cleaning or changes for me. A win-win to be sure. Those back spark plugs were _very _hard to reach, but it had to be done.
