Here's a shocker: Amazon is selling a $200 bracelet that will deliver a jolt of electricity every time you try to indulge in a bad habit.
"Pavlok allows you to speak your reptile brain’s language by adding an unpleasant element (a safe and harmless ‘zap’ of electricity on your wrist) to what you have been taught to love (your nasty lingering habit)," the manufacturer explains on the device's Amazon page.
If you choose, the Pavlok's 350-watt jolt can also be administered to you secondhand by family or friends who catch you in the act of overeating, smoking, biting your nails, or whatever gross habits you have.
It promises a reduction of bad habits within three to five days.
