re: Do we own our body? - Reminds me of The Matrix.
"We were interested in a classical question that philosophers and psychologists have discussed for centuries: why we feel that the self is in our bodies," project leader Henrik Ehrsson said. "To study this scientifically we've used tricks, perceptual illusions."
I'm not surprised by anyone asking the question or even by those that pursue to answer it.
Still, a bit scary.
As far as for the question, "Do we own our body". Yes, just be careful who you trusted to.
