But when the word human multi tasking started spreading it needed some research and concern.

Listening to music or singing while cooking, teaching a bit of maths while frying the potato is fine. Whereas talking on cell phone while driving is fatal.Failure to apply brake in a fraction of a second might mean life or death.

Now the researchers say that multitasking is a hype.We are not doing the multi tasking.What we actually do is shifting the attention from one task to another quickly.

According to Dr.David Meyer Ph.D ' for each aspect of human performance people have specific mental resource whose effective use requires supervision from executive control of the brain. This involves goal shifting and rule control. So the human brain has to shift and this takes longer time to complete the jobs'. This is the research finding.

So when we do multiple jobs out of compulsion or lack of time in todays scenario what we actually do is not multi tasking but multi shifting. This results in stress to the brain, lack of concentration required to perform a particular task and deterioration in the quality of work.

All these lead to frustration, pressure and mental depression. Plan and manage your time well. Never say that you dont find enough time. Iam reminded of an incident I read from a book on Sri.Rajagopalachari, second Governor general of Independent India and former Chief Ministre of Tamilnad. He had a habbit of replying to all the letters immediately and expected others to follow that.When somebody said that he was very busy that he went to bed only at 12 in the night and so could not reply to a letter, Rajaji said " you could have replied to the letter and gone to bed at 12.05."
