 Hm.. a little control computation:
 That makes per day 25W *24hours *60 minutes * 60 seconds = 2.1 mio
wattseconds
 (1 WS = 1 Joule, isn't it)?
 For example 100 g apple have 247000 J
 oule.
 So the brain alone needs the energy of about 800g Apples per day
 in form of glucose - and the vitamin b1 to process it properly.
 Not bad. >>
sorry, but this is simplistic, mechanistic and reductionistic---what that
things would be so simple...
