In the history of rec.scuba and scuba-l/se, Giovanni has
incontrovertibly proved time and time again the superiority of AI
computers over regular toys. In this instance, I'll bow to the
superior knowledge and intellect of Giovanni and his friend
Confucio. If they say so, it MUST be right. :-)

For the physiological part, I'd rather pass the buck to Esat.

Esat, could u pls try 2 xplain 2 Brad? :-)
