What if your employer gave you a Fitbit to wear and reduced your health insurance payments if you racked up the right number of steps?

"We think the device is easy to use, gets people aware of how little they are walking and helps trigger people to get active.... BP doesn’t see any of the data except in the aggregate." 

Yes, but isn't this creepy, the boss making you wear a bracelet that counts your steps? Meanwhile, Fitbit stands to do well if this catches on.

But how do they know who is wearing the device? You could snap that thing onto whichever family member is doing some exercise, including a dog running around in the backyard while you watch TV and eat potato chips.

You'll have to make the damned thing creepier to prevent cheating.
