Watching TV is already one of the top things to do when you're feeling lazy, and soon it'll require even less effort. UK telco Virgin Media is set to trial a new wristband that monitors your pulse and can tell when you've fallen asleep. It'll then beam a message to your TiVo and tell it to pause the current program and start recording it for later viewing. When you wake up, you can pick up right where you left off. Perfect for all of those food comas that are bound to happen over the holidays. The device — designed by a 14- and 15-year-old — will go into trials next year. Maybe someday the software behind it will make it to other fitness wearables, though there's no news on that front yet. You can sign up to be on the trial list right here.
