If you don't have the patience to wait for a smoking vaccine to hit your local pharmacy and don't have the willpower to quit smoking on your own, this fancy keychain could help you to stop slowly killing yourself. The Linkman gives you permission to smoke, acting like a concerned loved one and making you wait a certain amount of time between cancer sticks. When you get an urge to light up, you hit the button: if it flashes green, go ahead, and if it flashes red, you need to wait. It starts off with a 10-minute break between cigarettes and then increases by 0.39% with each cigarette. That's only a 2 second increase when you start using it, but the effect is a slow and methodical cutting back, allowing you to cut down to nothing after six months. Of course, if you really want a cigarette you can always ignore the red light, but if you actually want to quit and just need a little outside help the Linkman could be your ticket to an extra decade of life. — Adam Frucci
