Is it normal to check blood pressure yet smoke and eat junk?

Is it normal for someone to smoke cigarettes, eat junk food, and then, as baffling as this can be, check their blood pressure while gleefully imagining that it will be in the ideal range? I think that's equivalent to hitting yourself in the head with a large brick over the day, every day, assuming no bruising or damage will come of it.

People that do the above are the spitting image of futile dumb imbecile.
