The small town in Illinois where I went to college had an inexplicable wealth of thrift stores, and I quickly developed a thrifting habit. (“Habit” sounds better than “problem,” right?) I shared this secondhand lifestyle with my roommate, and we would do the rounds at the local shops at least once a week. For me there was (and still is) something deeply satisfying about the treasure hunt, the searching and discovery. During one of our forages among the dusty shelves, my friend found a light therapy lamp—one designed to mimic sunlight and shine on your face to combat seasonal depression.
