If you bought a bag of baking flour, say, more than a year ago, there's a good chance that flour has gone bad. Pull it out of the pantry and give it a smell. Does it smell rancid? If so, it's a good idea to toss it. But before you do, go grab the stacks of playing cards you have around the house. Throw the cards into a bag and cover them with the old flour, then seal and shake. The flour will coat the cards and take away the dirt, grime, odors and oils to make the cards fresh and clean. And then take all of the old flour and sprinkle it in the yard, it's biodegradable, and your lawn will love it.

If you drive to a train station and commute to work, should you park in an outdoor or covered parking lot in the winter months? If you can, park in a covered garage. Since your car will be outdoors in the harsh elements for the better part of the day, by keeping it in a covered garage you're actually keeping the car a tiny bit warmer. This extra protection from the elements helps you bring the engine to the optimal temperature much faster, which means better fuel efficiency for your car.
