Researchers in India have designed a way to find out if someone is sick just by sticking out their tongue. But you don't have to be in the doctor's office to find out. A group of technical engineers have designed a digital tongue analysis software to help people in remote areas who may not have access to a physician. What can your tongue tell a doctor about your health?
And if that isn't cool enough, the researchers say next they'll be adding eye images to their repertoire of digital images to help diagnose even more diseases.
