I only have wallpaper in a cat house because it was there when I moved in, about 8 years pre-cats. Don't see the point of changing inoffensive wall coverings just because they are over a certain age.
OTOH an ex work mate of mine always seemed to be redecorating. When I asked why he hadn't finished, he explained that his wife insisted on every room being redone from scratch every 2 years. OK not NEW bathroom & kitchen fixtures, but repainting in those rooms & new lighting fixtures etc., new everything in all the other rooms including carpets, lights, furniture. When I asked him how much it was costing them every 24 months he went a bit green round the gills
