Wow. I've only been a cyclist for about a tenth as long, and I don't have anywhere near that amount of stuff. I guess it's an exponential function.
That being said, if someone wants a glass of water at my apartment, I direct them to one of the many full bike-bottles in the 'fridge. I can fix any number of squeaking or rattling things because I have ample quantities of White Lightning, Tri-Flow, solder, and various forms of bicycle-friendly glue. My bikes occupy the same spot on the wall as do my neighbors' television sets.
