One thing I forgot to mention, which is positive in nature, is that I've prevented several house and car fires by smelling hot electrical smell in time to do something about it. I learned to "listen" to my nose after I nearly lost my restored classic Cadillac to a an electrical fire... A friend and I were taking turns driving it back to Los Angeles from Las Vegas, and I kept smelling hot plastic. My friend (age 70 & can't smell), said I "was imagining things, and just keep driving". About 20 minutes later, the headlights went out on Hwy 138 in the middle of the Mojave Desert, and I felt my left foot getting hot, and the car was completely full of waxy smoke! I had to stamp out a small fire in the carpet by the hi-lo headlight beam switch, which had started due to a loose plug. Close call!! !! ! It had melted to the point where I couldn't fix the connection in the middle of the night with no tools, so we drove it all the rest of the way with the blinkers on and the headlight power disconnected for safety. I have also caught a CFL light bulb in the house, which was starting to smoke and drip burning plastic in another room! My wife didn't smell it, and the smoke alarm didn't go off 'til I pulled the burning bulb out.
