How stressed is your spit?
Over in Japan Yamaha in collaboration with Nipro Corp and researchers at Toyama has developed a gadget that can tell how stressed you are by analysing, wait for it, your spit.
According to a news report on I4U it works by measuring amylase which is a digestive enzyme found in saliva. Apparently the more stressed you are the more amylase is present.
The company hopes to have a gadget available for both institutions and the Japanese public later in the year.
