Look for dirty spots in your insulation, which often indicate holes where air leaks into and out of your house. You can seal the holes by stapling sheets of plastic over the holes and caulking the edges of the plastic.
Winter means snow, and snow means shoveling. Invest in a plastic shovel because metal is a lot heavier. Choose a shovel with a curved handle to improve flexibility. Pick a shovel with a deep bucket so that it will hold a lot of snow. Place one hand near the base of the shovel with the other grasping the handle while lifting snow. Spray the bucket with a lubricant, such as Pam cooking spray, to help snow slide off easier.
