I never realized how much personal smells are the result of emotions, rather than exercize. The whole 2 months at my meditation retreat, I had the interesting experience of having very few real emotional exposions. I learned that emotions follow particular thoughts, and that if you don't cling to the emotions, they will pass away on their own in a couple of minutes, leaving no smells or thoughts. As a result, the body stays clean on its own, and you really don't need to shower often, wash clothes, and you lose your own general smell. Almost like you lose your person-ness when you don't get lost in your emotions, which is what I generally do in the city. You don't need to cover up emotions, but rather you just ride them out and develop an awareness of them as they move through you.
Now that I'm back in the city, I notice smells again. Even in this simplistic life of no work and no worries, the smells are back. Not as much as usual when life is a whirlwind of emotions, but enough to notice.
