Drinkin' a smoothie in half-hero

I know every parent is blown away by their baby's flexibility. When do we lose our ability to sit ever-so-comfortably in half-hero pose with a perfectly straight spine? Is it because of the dreadful desks we're forced to sit in for hours and hours? Is this yet another argument against standard education...we lose our flexibility, literally and figuratively, because of its emphasis on conformity?
