Save Energy and Keep Your Breasts Warm and Toasty
TreeHugger always advises turning down the thermostat and putting on a sweater, but different parts of the body react to cold differently, and some need a little more help than others. The USB powered breast warming pads to the rescue. Just plug them into your computer and stick the U-shaped pads under your bra and problem solved.
The google translation of the website says that they will quickly warm up to 40 degrees C, or a cozy 104 degrees Fahrenheit. They cost about $20, but I cannot tell if that is for one or for a pair.
