Introduction `Man is a multi-sensorial being; occasionally he verbalises.' Ray Birdwhistell, American anthropologist How it all started Occasionally he verbalises! Even before you uttered a word you could communicate. Every mother knows her baby's different cries ­ the cry for hunger, the cry of discomfort, the cry of pain and the cry for not getting your own way. Even before you understood a word you understood a smile, a frown and perhaps even a look of anxiety.
