I can totally understand the "addictive personality" bit mentioned.
With me its been everything at one time or another apart from gambling.
Beer, fags, sex, photography, judo (training 3 or 4 times a week at one stage), motorbikes (about 40), tuning cars, certain naughty substances in my formative years (seventies) and of course Hi-Fi still. I think the family like me having that obsession as it keeps me out of the way, costing me money though and I've got to thin down the collection.
