Make your days longer: Machine Gives Full Night's Sleep In 3 Hours
@ 2007/05/07University of Wisconsin-Madison researchers have invented a machine that makes you sleep with the PUSH OF A BUTTON, then gives you the equivalent of eight hours of sleep in just two or three hours. The machine uses a technique called transcranial magnetic stimulation (TMS) to induce the slow brain waves associated with the deepest phases of sleep.
I feel an urge to invest in the magnetic wristband = arthritis cure market now.
