Kate Beckinsale Smoking at the Gym

I'm confused. First off I don't get smoking. I mean, yeah, I know why people do it, and even why they might start, I just don't get it. On a logical level, it makes no sense, and everyone knows it. But how do you go from working out, and getting into shape one minute, to smoking a cigarette in the gym parking lot a minute later? I guess Kate Beckinsale's work out regimen is less an issue of health, and more an issue of body image. Which makes sense, since she's an actress, and all. Still, I'm confused.
