i hope there's time to 'flesh this idea out' before it evaporates!
i think that there is a massive increase in body image and eating disorder issues world wide and this connects to the globalisation of mass media PLUS the increase in wealth (side issue - more of the world's poor are fat than skinny these days... although skinny is still starving to death) .
having just explored facebook i am feeling more optimistic about our ability as a society to restore the body image balance. the surge in facebook and web 2.0 social networking allows us the freedom to create connections unrestricted by our physical presence and whatever body image issues (dysmorphia) we have can become secondary... or can be explored.
perhaps this is the real avatar assault!
