Visions under psychiatric supervision. It is dangerous for mountains to encompa** my myopic vision. Leaping from cliffs must but now be a virtual game. If I can't see, judge distance and wind current, if wing feathers are gray, the abyss which I think to glide into, cushion my landing with a knee bend, and grab a rat, the abyss will break my bald head, brains will splutter and hiccup on weathered stone.
