Research Suggests Brain Has a 2-Task Limit for Multitasking
suraj.sun writes with a story from LiveScience about just how much attention you can devote to each of the tasks on hand that scream for it: "The brain is set up to manage two tasks, but not more, a new study suggests. That's because, when faced with two tasks, a part of the brain known as the medial prefrontal cortex (MFC) divides so that half of the region focuses on one task and the other half on the other task. This division of labor allows a person to keep track of two tasks pretty readily, but if you throw in a third, things get a bit muddled. 'What really the results show is that we can readily divide tasking. We can cook, and at the same time talk on the phone, and switch back and forth between these two activities,' said study researcher Etienne Koechlin of the Université Pierre et Marie Curie in Paris, France. 'However, we cannot multitask with more than two tasks.'"
I call bullshit. Right now, I'm replying to this Slashdot article from my cell phone, eating a quick breakfast, and driving my car in morning traffic. I'm doing all three with the utmost saf

Pick two.
Go green: turn off your refrigerator.
Seriously though, you might be able to learn how to do that if you could practice doing that 100 times every day, for a month under safe simulated conditions (e.g. driving simulator, and simulated eating too, otherwise you'd end up killing yourself by overeating ;) ).
It's all about practice. Practice, practice, practice.
The first time you drive a car (especially a manual), there are so many tasks.
After a while of practice, your brain configures itself to automatically make those tasks into a subtask, and groups them all into one task - "driving".
Of course some people may never be able to do it. But I think a high proportion of people can. And I bet there are some people who can learn to do it after very short time - just like some people can learn to juggle very quickly, and there was that recent article about supertaskers.
I'm sure Michael Schumacher can eat breakfast and type on a cellphone and still do F1 laps faster than I can, when I'm just doing F1 laps (just driving, not eating or doing other stuff).
The trouble with most people is they're trying to do "for real" without practicing _properly_. That's like trying to juggle chainsaws, without learning how to juggle balls first, and then gradually working your way up under controlled conditions.
No one wants to beat that
my karma will be here long after I'm gone
