I knew a kid in college, whose parents were both packrats... I went over their house once, and they had whole rooms devoted to pure crap... like old gift baskets, electronics from the 70's, board games, you name it they had it. Their basement was literally a labyrinth of junk (a total fire hazard), and their dining room table was covered with a mound of chachkas almost as high as the ceiling.
I'd never want to live like that, minimalism FTW.
