STRESSED OUT? JUST SPIT HERE, PLEASE

A Japanese firm has created a handheld gadget to check stress levels by analysing saliva, allowing people on the edge to check their frayed nerves as frequently as they want. The "Cocoro (Heart) Meter" has a chip which a person moistens with saliva and sticks into the machine to discover his or her stress in one minute.
