I’ve known and worked with many mechanics, and I would say that 60-70% of them were smokers. My buddy JR was the heaviest smoker I knew. That boy could breathe Diesel exhaust if it was fed to him. And he was ripped. I remember the first time I saw him shirtless. I got a boner so fucking hard. And I still masturbate to him to this day. And that was 25 years ago.
