You may have an illness and not even know it -- and the proof could be on your breath.  That’s because our bodies give off complex aromas, some too faint for the human nose.  And when sickness alters cell metabolism, an array of telltale volatile chemicals make their way into our breath, urine, and sweat.  Now, research labs around the world are figuring out how to use gas sensors to detect disease.  Here are a few aliments they’ve gotten a whiff of so far:
