remember when the government telling you what to do was scary?

An avatar generator for a virtual environment reflects a physiological characteristic of the user, injecting a degree of reality into the capabilities or appearance. Thereby, many of the incentives of the real world are replicated in a virtual environment. Physiological data that reflect a degree of health of the real person can be linked to rewards of capabilities of a gaming avatar, an amount of time budgeted to play, or a visible indication. Thereby, people are encouraged to exercise. Physiological data that reflect the health and perhaps also mood also improve social interaction in virtual environments. People seeking to meet and become acquainted with particular types of people are not thwarted by the artificiality of avatars. The physiological data can be gleaned from a third party health data collection repository, a healthcare smart card, a real-time physiological sensor (e.g., blood pressure, heart rate, blood glucose, peak flow, pedometer, etc.)

from Patent Application: Avatar Individualized by Physical Characteristic

Yes Microsoft, because no one who's fat has ever been told to work out before. Because no one anywhere has any physical limitation preventing them from working out. Because it's your place to build an application that does this. Because all of us need Daddy Microsoft's approval before we can have any fun. Because online relationships are inherently inferior to real life ones.

Yeah, you know what, Microsoft? Fuck you.
