Back when my wife was the thin girl next door she was the type that really had no vices. Now years later she has more than a few of them, one of which of course is food. She will always admit that she feels that she is addicted to food. Is she also addicted to weight gain or is she addicted to food and therefore gains weight. She has loved getting fat over the years but is that an addiction. I also wonder, can one addiction lead to others? It wasn't until she became heavier that she started smoking and she didn't start smoking to lose weight. She has also become a much heavier smoker as time has gone on(no pun intended). She comes from a very addictive family but she herself was never the addictive type. All of the vices she now has have come since she became heavy. I just find it interesting how things happen.
