Why do people still smoke?!?

I take my dogs on a walk every morning. This morning, I opted to exit out of the riverside of my apartment building (an old cotton mill) and nearly stumbled over a guy sitting on the steps - in his pajamas - smoking. At 6:30am. Did I mention he was in his pajamas?

I am baffled. I don't understand why people smoke, but the sight of this guy barely awake and puffing away totally boggles me.

I can't think of a more unappealing way start the morning. My walk, which comes with plenty of fresh air, did wonders.
