This is pretty interesting. Read the whole article. Happened to bump across this contemporaneously with my experimentation with the PersonalBrain knowledge management software.
People have long envisaged the brain as being like a computer on standby, lying dormant until called upon to do a task, such as solving a Sudoku, reading a newspaper, or looking for a face in a crowd. Sokoloff’s experiment provided the first glimpse of a different truth: that the brain enjoys a rich private life. This amazing organ, which accounts for only 2 per cent of our body mass but devours 20 per cent of the calories we eat, fritters away much of that energy doing, as far as we can tell, absolutely nothing.
If I offload a lot of the brain work to the software will I gain weight?
