心情的好壞＝對事情的看法？是嗎？

【Clips】Eight Hours of Sleep a waste of time?

With reference to the clip below (from clipper), I really wonder in this world of ours, what’s not a waste of time? Why are we so short of time? Are we too slow or do we just aim for too much and thus end up with too many to do?If I’m given the choice, would I choose to be zap? I guess I probably won’t ‘coz though I’m also always short of time but I do believe that even if I’m zapped, I would still be short of time ‘coz I would definately aim for more and thus have more to do and the cycle goes on…

What about you? Would you or would you not? Share your thoughts…

Zapping your brain with an electromagnet could do the trick.

A good night’s sleep just takes too long. Scientists may soon be able to cut those eight wasted hours down to three or four—by waving a wand, more or less.

The technique, transcranial magnetic stimulation, involves an electromagnetic coil that emits pulses of skull-penetrating, neuron-activating magnetic energy. Depending on where the wand is and how fast it pulses, TMS can play all kinds of tricks. It can make a thumb twitch, create the illusion of a flash of light, or even treat depression. Neuroscientist Giulio Tononi of the University of Wisconsin set out to see if TMS could switch on certain sleep phases.

Electronic naps are a long way off, though. Between the armchair, the clicking coil, and electrodes, “it’s clearly not a machine that you can use at your house,” Tononi says. “It’s actually hard to get the person to sleep while doing these magnetic stimulations.”
