One of my friends runs a game shop. He told me a wealthy surgeon would come in weekly and buy $5,000 worth of baseball cards - either as singles, boxes of unopened packs, or whatnot. I remarked that the surgeon must really enjoy the hobby. He replied that the surgeon looked exceptionally distraught every time he made a purchase, but did so regardless.
It's just anecdata, but being able to support an addiction doesn't mean you have control over it, nor that you're happy about having it.
Speaking of which, it's time for me to get off HN and do some real work.
