What you're referring to might be olfactory resonance syndrome you can get psychological help for this from a professional. if someone mentioned it in work 1 time in your life only, maybe that was the work environment or a passing thing. Most ppl with bo have been confronted on it numerous times in numerous places and they pretty much know they smell. if your smelling something i read about some people who have something in their sinuses causing them to smell something there. i believe there's more written about that on this page. if so, you could check it out with an ear nose and throat doctor.
