As the Sun bakes the northeast with triple-digit temperatures, it's a good time to review the important ways to keep yourself from overheating: 1) Drink lots of water, 2) Take it easy out there, and 3) Remember to swallow your CorTemp thermometer. Yes, now high-tech thermometers come in convenient pill form, going down the hatch with a swig of water. The amazing ingestible CorTemp Core Body Temperature Monitoring System does exactly what is says on the tin, continuously reading your body temperature while it slowly drifts from esophagus to colon, transmitting the readings to an accompanying handheld. The Philadelphia Eagles and the Minnesota Vikings football teams use the CorTemp system, manufactured by HQ Inc., to ensure their players don't overexert themselves during practices. From the look of this cross-section of the pill, it's pretty sophisticated — we hope not so sophisticated that the little probes aren't disposable. That could lead to a whole lot of stuff we don't ever want to think about. Thanks for sending this in, R.J.… we think. — Peter Pachal
