I ran across a very cool experiment while doing some research for a project (yet another great thing about university-- I would never have found this if left to myself): One Tonne Life. It's kind along the lines of No Impact Man, really; the Lindell family have moved into a newly-constructed, climate-smart house, where they will live for six months. Some major brands, like Volvo and Siemens, have contributed to this project, the idea being (as I understand it) that they can both get their names associated with green living and also can give new, eco-friendly products a test run.

So, tell me: It doesn't have to be environmental, but what's a change you've made in your life that has had unintended, but welcome, side effects?
