Well... that might be all good and swell if you're immobile and dormant for long stretches of time. But most of us need to still go around, move and work to live :P

Interesting research none the less.

Have you heard of "breatharians"? People who claim to not eat or drink and recycle their saliva, etc. Interesting possibilities, but not something one can simply "try" and succeed at.

Take care. Peace.
