Right, but then the question remains why is the lower back cooler in the picture as well. Is the blood flow through ones entire back flow through that area first? Which of course made me think the correct placement for it would be somewhere with a lot of blood flow near the skin that could be cooled a couple degrees. I was thinking the inner thigh might be a good place, but the device isn't shaped correctly for that, given your just going to cool one side, and cook the other.
