Bluetooth epidemic!

I was at the gym tonight when I spotted not one but at least 2 people randomly talking to what appeared to be no one. The word "crazy" went through my mind but it quickly changed to pity for the person they were talking to. Imagine talking to someone who was (assuming their heart rate is above resting) exercising? Can the other person even make out what is being said? Will the person wearing the tooth suffer from electrical shock if they begin to sweat? (again, assuming their heart rate is above resting) . There is a reason they didn't come up with this invention earlier, I honestly think that if whatever your doing requires both hands; chances are you shouldn't be on the phone. I will use all my will to refuse the seduction of the tooth! (blue or pink...do they come in beige to match my shirt?)
