Multi-tasking is just like playing a memory game. The Avg person can keep about 7 things in his/her head at one time. In order to improve those aspects of your short term memory you have to continutely test those limits. I'm not saying to sit down and play the memory game, but rather when ever your doing something, combine the different tasks at hand so that you can take on more at a faster rate. This could be anything from getting ready in the morning to a research project online. (which involves a great deal of multi-tasking especially if your using three or four programs)
-Although I can only imangin the fright-ful level of multi-tasking in a multi-million dollar aircraft such as a fighter-while other people on the ground and in the air have only one objective and that is to bring you down. thats got to be pure insanity.
