Nokia has a wacky new concept phone that could just save your life, mister. The dual device would function as a cell phone (like most of Nokia's products) and a sensor that could monitor the user's health and environment.
The monitoring device would most likely be worn around the wrist or neck.
With this device, it will be possible to detect exactly how stressful it is to talk to certain people based on the changes in heart rate and perspiration.
