I suppose I really ought to quit smoking. But I bought a carton of smokes last week and I've still got 6 packs left. Besides, smoking's my muse, it ignites my brain cells.
Smoking gives you cancer. You could get lung cancer, even brain cancer. Cancer's a horrible, shitty, deadly disease.
If I quit now I'm leaving 6 packs of cigarettes unsmoked, unappreciated. They don't let you return those things to the store you know.
It could be those 6 packs that push you over the edge and give you cancer. You'll die a terrible, miserable death. Your hair will fall out. Oh wait, OK, your beard will fall out. You'll have to lie in a hospital bed all day. You hate that. And there isn't really a cure, so you'll linger in pain and sadness until the day you die.
But if I quit now I'm out 20 bucks.
