One more thing. I think we (bike commuters) obsess too much over how we smell at work. The fact is that human stink is more a result of not bathing rather than sweating. When men stink, it's most often the result of sitting one ones' ass all day without having bothered to shower in the morning rather than hard work or exercise. I would almost go as far as to say that driving makes me smell worse than riding my bike.
More on that later.
