Valorous Visitation of a by-gone Vexation

Human beings can be pretty strange at times. They know that some things are bad for them but yet they keep having the urge to do it. Take shopping for example. You know you already have a similar item at home and you DO NOT need the new item. Somehow, you just pick the item up and before you know it, you are on your way home with something which you don't really need together with an unnecessary hole in your wallet.

Is this what they call the Shopaholic syndrome? If it is, someone please light a path for me.
