I mention this only because yesterday I had a realization. The weather is rapidly turning towards winter, and being the perennially cold and thin-skinned individual I am I found myself curled up in the recliner with a thick blanket and slippers on, shivering and wondering where I'd hidden the small electric heater that usually resides next to my dresser. (Last winter I spent several hours huddled over this miniature power hog with a blanket over my head, attempting to create a one-woman sauna hot enough to peel off my outermost layers of skin. It was only after getting the electric bill for the month that I reluctantly put the heater aside, but I couldn't bring myself to get rid of it all together- we were far too close for that.) The blanket wasn't really doing the trick, and I couldn't recall which closet the heater had been relegated to, so I decided to see if the hot water bottle I'd purchased on a whim last summer might work. I was fairly certain it was hidden somewhere under the bathroom sink, so I put the kettle on to warm up while I fished around between shampoo bottles and rolls of paper towels before emerging triumphant and heading back to the kitchen.
Wonder of wonders!!!! These things hold heat forever, and you don't have to plug them in! I could wander around the house hugging my happy red bag of warm, and I wasn't limited by the length of a cord! And did I mention it's warm????
It may not be the latest technological marvel (maintains-a-temp-of-101-degrees-24-hours-a-day-only-19.95-order-now!), and I'm no Luddite, but by golly it does the job well and simply. How could anyone not be satisfied with that?
