Why We Can't Do 3 Things at Once

A new study says that human brain is setup to do maximum number of 2 tasks at a time, but no more than that. Here is an extract from Livescience.com

"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."
