Except for when your health insurance company sees that and starts charging you more because of it, or your life insurance rates go up because of it, or your homeowners insurance goes up because of it, or your employer forces you into a smoking cessation program because they made you sign some kind of "smoke free pledge" for their own insurance reasons and now they think you're lying, or when someone decides not to date you because the background check they ran on you made them think you lied in your online dating profile when you said you didn't smoke, or when society gets real weird in the future and smoking goes from being "unacceptable in public" to "child abuse" and now CPS is wanting to investigate you, or who the hell knows what other thing could come and bite you in the ass now that you've got "smoker" in your permanent record and everybody feels entitled to dig into your personal business whenever they think it might give them some advantage.

That's the world we live in. Anybody willing to pay gets to look into the most intimate parts of your life that are none of their business and that ends up affecting your life in ways you'll never see coming and you'll probably not even know why or when it's happening. The more data you put out there for people to find, they more they'll find ways to screw you over with it.
