I've noticed that since I got married, the number of containers I store on my desk against the coming aluminum can and mold shortage has dropped drastically. And since I no longer smoke indoors, I've no need to store pounds of ash and thousands of filters within easy reach.

Of course, I still voted 4-6. I'm an old rat, and picking up after myself is still a relatively new trick ;)
