My stuff includes dozens of glasses I've never used, a small aquarium supporting no visible life, and a weight-lifting bench that's quickly evolving into a storage shelf. But my stuff is nothing compared to many people's. Some people live in large houses and own so much stuff, they often have to spend days searching for their children. If you're suicidal and can't hire Dr. Kevorkian, just visit one of these homes and jerk open a closet. In America and most wealthy nations, accumulating stuff is one of the most popular hobbies.
People love to shop and they also love to collect things.
People also like to save junk, often for no apparent reason than to give the trash man a break. A friend of mine has saved every greeting card she ever received. Some day, when she's old and gray, she'll have enough time to take them out, spread them in front of her, and wonder whether she was once on drugs. Many people can't seem to distinguish between good stuff and bad stuff. Good stuff is stuff you use.
