Not content with knowing where you go, both in real and cyber space, Google will soon know how much you weigh too - thanks to wi-fi-connected scales.
The scale in question come from Withings, and it was launched last year with connections to various fitness websites and an iPhone application. But now Withings has managed to integrate its monitoring software into Google Health, allowing users to share their current weight with the chocolate factory without leaving the comfort of their own bathroom.
Ideal for tracking the whole family, as long as there aren't more than eight of you, the WiScale can work out your body fat and calculate your Body Mass Index - should you wish to trust that particular metric.
All that technology doesn't come cheap: you'll need to shell out near on a hundred quid ($160) for the scale, and it doesn't even link to your Facebook account to Twitter to your Weight Watchers group - at least not yet. ®
