It's like how I learned how hard a "salesman" works. My dad was in sales my whole life and I bought into the BS that it wasn't really "working". LOL I sure learned what a bunch of crap that was in short while! I remember being out on the road and calling him to thank him for how hard he worked to put food on his families table. It was MUCH, harder physically than working on cars every day. That includes working in the office now, it is MUCH harder physically on the body. I got clean clothes and walked from the shop into the office, I am not blowing air out of my butt. Other than a hard day on the frame rack or blocking complete cars, it is MUCH harder what I do now than hanging quarters and such. But tell that to a guy who has never worn the other hat, oh my God, you are a lying piece of crap.
