British thinker and Statesman Lord Crisfield said that man has all the time to do all jobs provided he does them one after another. If he attempts at doing two jobs at the same time, then even one year of time is insufficient to complete the task.
Nowadays multi-tasking is turning into a trend and in fashion. Many types of investigations find that it can prove to be fatal. According to Earl Miller, a neuroscientist from the MIT says that if people feel that they are doing two things at the same time, then this is their misunderstanding. In reality, their brain leaves a job and takes up the second, and then leaves the second to do the first one. So, in real time it is one job at a time.
Multi-tasking is harmful as per a research in the London University. The conclusion shows how such situations disturb and disorganized the thoughts process. The flexibility to filter irrelevant information gets affected, and the capacity of output and quality of the work suffers. The research pointed out that it lowers the IQ. It is similar to fact without proper sleep the output is like having an intoxicated effect due to marijuana the previous night.
It is a well-known fact that the hormone cortisol increases in quantity due to multi-tasking, and the person in action gets overstressed. In another research, it got noted that working on more than one device (like watching a TV serial and sending out a message) the MRI scan clearly showed that people who often do the multi-tasking the part of the brain where the finer feelings get generated become impeded. Many such researchers have indicated that nothing unusual happens due to multi-tasking that needs appreciation and that the trend needs a total stoppage.
