A fringe benefit of wearables is finding out if your loved ones aren’t dead
Imin a London branch of the Apple Store, about to buy a pair of Apple watches. Place two fingers on the screen until you see and feel your heartbeat. Lift to send, says the website. This heartbeat, I ask one of the salespeople, is it his actual heartbeat? Like, could I analyze it for irregularities or defects, if I was a doctor? So, I pass on the watches for now, but at some point theyll probably update that feature....
