　　Why is it that flying to New York from London will leave you feeling less tired than flying to London from New York? The answer may be a clear case of biology not being able to keep up with technology.
　　Deep inside the brain there is a clock that governs every aspect of the body's functioning: sleep and wake cycles, levels of alertness, performance, mood, hormone levels, digestion, body temperature and so on. It regulates all of these functions on a 24-hour basis and is called the biological clock.
　　This body clocks programmes us to be sleepy twice a day, between 3-5am and again between 3-5pm. Afternoon tea and nap are all cultural responses to our natural biological sleepiness in the afternoon.
　　One of the major causes of the travelers’ malady known as jet lag is the non-alignment of aperson's internal body clock with clocks in the external world. Crossing different time zones confuses thebiological clock, which then has to adjust to the new time and patterns of light and activity. To make matters more complex, not all internal body functions adjust at the same rate. So your sleep/wake may adjustto a new time zone at one rate, while your temperature adjusts at a different pace. Your digestion may beon a different schedule altogether.
　　Though we live in a 24-hour day, the natural tendency of the body clock is to extend our day beyond 24 hours. It is contrary to our biological programming to "shrink" our day.
　　That is why traveling in a westward direction is more body-clock friendly than flying east. NASA studies of long haul pilots showed that westward travel was associated with significantly better sleep quan­tity and quality than eastward flights.
　　When flying west, you are "extending" your day, thus traveling in the natural direction of your in­ternal clock. Flying eastward will involve "shrinking" or reducing your day and is in direct opposition to your internal clock's natural tendency.
　　One of the more common complaints of travelers is that their sleep becomes disrupted. There aremany reasons for this: changing time zones and schedules, changing light and activity levels, trying tosleep when your body clock is programmed to be awake, disruption of the internal biological clock andworking longer hours.
　　It is often suggested that you adjust your watch as soon as you board a plane, supposedly to try to help you adjust to your destination’s schedule as soon as you arrive. But it can take the body clock several days to several weeks to fully adjust to a new time zone.
　　So, our body clock truly can "govern" us.

　　After two decades of discredit, Keynes' prescriptions for state intervention when free markets stum­ble have returned to dominate the national agenda. For example, any solution to the problem of federal budget deficits will probably involve raising tax revenues and also stimulating employment, the traditional Keynesian priority. Another of the economic blueprints calls for hiking income taxes while encouraging in­vestment through restored tax breaks for business. To offset higher taxes, neo-Keynesians revise the old remedy by lowering interest rates, spending less on public works and boosting productivity through the de­velopment and application of high technology. "The urgent need," says Harvard's Summers, "is to bal­ance the federal budgets and create jobs.”
　　To some extent, Keynesianism has come back into favor almost by default. Monetarists, let by University of Chicago Professor Emeritus Milton Friedman, espoused their single-minded program; Fend offinflation by strictly controlling the money supple and leave everything else to the free-market which on itsown produces as much growth and employment as an economy can sustain. While supply-siders like Arthur Laffer suggested deep tax cuts in the belief that they would unleash entrepreneurial energy and easeWashington’s stranglehold on the free market. But the two doctrines have proved unable either to staveoff or to explain the recession during the George Bush administration. Freemarket theories just failed tobuild a viable set of models.
　　Keynes also owes his comeback to an articulate group of young academics. Among the rising-star disciples are Harvard economist Jeffrey Sachs now knows as "Father of the Shock Therapy," and MIT's Alan Blinder, current economic advisor to President Bill Clinton. "The traditional Keynesian reflex to re­duce unemployment merely by pumping up spending," says Alan Blinder, "is gone forever." He aims at balancing the federal budget and raising investment primarily by increasing taxes. Sachs also argues that more than half of the deficit gap should be closed by tax increases. Both of them urge greater coordination among the G-7 on fiscal and monetary policy as the only way to head off a global recession.
