A Distorted Tally System?

Here's a question: Does physical activity (walking, running, yoga, Pilates, etc...) cancel out a bad habit (smoking, drinking, eating poorly, etc...)? I pose this question because I was struck today by two such cases of this very question. First thing this morning, I saw a woman circling my block in a repeated fashion. While there was nothing absurd about her track suit or runners, I was taken aback by the fact that she was puffing on a cigarette in between strides! She was literally a speed walking conundrum!

The second example arose when I saw another woman fully decked out in Lululemon Athletica gear (including bag) and like the first woman, she, too, was puffing away on a cigarette while she waited for the bus. While I understand that Lululemon is now ubiquitous and anyone can sport the products, I would have thought that maybe some of their good-feeling marketing about energizing one's body would have sunk into the minds of those that opt to shop such stores. Then again, maybe it is just me and my distorted sense of mathematics - I don't think the two cancel out!

Incidentally, if any followers are keeping track: 3 regular beers are enough to wipe out the sweat and time spent in a 60-minute workout session, at least calorie wise!
