I would agree conditionally that, "Only if you want them to.", is true.
My case: I stopped smoking cigarettes unplanned and unexpected on 1/15/2010, the same day my first PV was delivered. I had no conscious plan to quit smoking, not even on my radar. I bought the PV merely as a curious gadget. But, to my amazement, I dropped the smokes with zero effort. And, again, totally unexpected to me.
Perhaps I was subconsciously ready to quit. But, consciously I was a bit terrified of the prospect. To this day, a year and a half later, I'm still amazed that I'm no longer smoking cigarettes (when I stop to think about it). I smoked a carton per week for about 35 years.
So, "only if you want them to", could very well be an unconscious desire.
