Maintaining a marathon runner's optimum body temperature is vital.  So sports outfitter Adidas asked George Havenith, a British physiologist, to map where our two to three million sweat glands work hardest.  Turns out it's not necessarily the body parts most prone to overheating.  Adidas then engineered a custom human air-conditioning system that includes ribbed fabrics to disperse sweat flowing down a runner's sides, and silver-coated yarn that radiates heat from their backs.  Such technologies are cooling marathoners from head to heat-prone big toe.  With the National Academy of Engineering, Randy Atkins, WTOP Radio.
