I am myself a collector, I did this since childhood and haven't cured until today, the thing is I moved from the house to a small appartment with my gf and since then all my collectibles are stuffed in boxes in a wardrobe.
I collect a lot of [censored] from bubble gum cards to Motorola cell phones, from bottle caps to fitness and karate magazines. I love all my collections and will never throw them away, on the contrary I start more and more collections everytime I like an idea.
