I'll throw in my two cents worth! Years ago, I worked with a fellow who was very nice, but quite uptight because he was stuck in a retail store rather than his choice of careers -- he was really too old to be in this particular store (I was older, of course, but managing the place - Haha!).
Anyway, one day I was standing next to him and he actually smelled like manure. I could not believe it -- that was when I was doing more juicing so maybe my sense of smell was heightened.
I just put it down to his being so angry at having to work beneath his abilities (which he could have pursued more vigorously perhaps!).
