A robotic massage chair is a chair that contains internal electronic motors and gears designed to massage the person sitting in them. Most robotic massage chairs have some form of controller to vary the type, location, or intensity of massage. The first electric massage chair was invented in Japan before World War II.
Temperatures at Everest Summit and Base Camp The coldest temperatures of the year occur from the 15th of December onward until the end of January with temperatures at the summit averaging -37C (-35F) while those at Everest Basecamp average -17C (1.4F).
Suppose you're on top of Mount Everest and you're bundled up; your core temperature is 98.6 degrees F. If you take off your gloves, you have exposed that area and it may get frostbite.
