Could Using a Bluetooth Tracking Device on Yourself Help Decrease Your Anxiety and Improve Productivity?Or would the security and privacy concerns prove to be too much of a burden?

When Eric Sanchez first bought a Tile — aBluetooth-connected tracking device for absentminded consumers — he initially did what many people do: He stuck it on his wallet. "I've been late to meetings because I can't find my keys or wallet, and that's terrible," he says.

Then Sanchez realized Tile might solve an even larger, more personal issue. He is the CEO and cofounder ofRevl, a video company that usesAIto record personal highlights in fast-moving environments like skydiving, and he has done more than 200 jumps himself. Now he plans to stick a Tile on his parachute so he can find it if he ever has to cut the line and use a backup.
