The ability to do several things at once has become one of the great measures of self-worth for 21st-century Americans. It is called multitasking, and it takes many forms. As one example, why go out to lunch when you can eat at your desk, talk to a client on the phone, scroll through your e-mail, and scan a memo simultaneously? And why simply work out on treadmill(单调的工作)when you could be watching television and talking on a portable phone at the same time? What a feeling of satisfaction and accomplishment—three activities for the time commitment of one! Ah, such efficiency. No wonder those who turn "to do" lists into a time-management art form are inclined to boast, "Look, me, how many things I can accomplish at once. If I'm this busy, I must be important."
Yet last week the New York Assembly struck a blow against multitasking, at least behind the wheel, when it approved a bill banning drivers in the state from using handheld cellular phones. Too dangerous, the assembly said, citing research showing that drivers are four times more likely to have a collision when they are talking on a cellphone.
No one can argue against using time effectively. But accompanying the supposed gains are losses. Consider the woman out for an early-morning walk in a suburban neighborhood. She strides briskly, head down, cellphone clamped to her ear, chattering(喋喋不休)away,
oblivious
of the birds and flower and glorious sunshine. Did the walk have any value?
More than a decade ago, long before multitasking became a word in everyday use, a retired professor of theology in Indiana with whom I corresponded made a case for what might be called uni-tasking—the old-fashioned practice of doing one thing at a time. Offering the simplest example, he said, "When you wash the dishes, wash the dishes." Good advice, I've found, whatever the task.
Perhaps, too, the ban on phoning on the road will even spark a move away from other forms of dual activity. Who can tell? It could mark the first step in a welcome reconsideration of what really constitutes productivity and accomplishment.
