Further to the MAN - WOMAN analogy it is due to a physiological difference
between men and women.
Women have their left and right sides of the brain linked by more neurons so
they can multiprocess
Men can't because they have a limitation in their left to right hemispere
communication
(Feel free to use this trivia next time a woman says you are not listening
to me - because you are
watching TV)
So its a bandwidth problem
Could be extended to the problems of WANs vs LANs
