A scientific case to take more vacations to places you've never been -- so you can feel like you're living longer.
"[David] Eagleman has shown that when the brain is exposed to the same image over and over, and is then confronted with a different image, the new one seems to last longer, even though it is displayed for the same period of time. The brain also uses more energy when exposed to the new image. "The length of time something seems to have lasted appears to correlate with the amount of energy the brain uses to record an event," Eagleman says.
This observation may also help explain why time speeds up as we get older. For children everything is new and the brain is processing vast amounts of information about the world. As we age and the brain has learned the rules of the world, it ceases to record as much information. "It is as if at the end of a summer you look back and you don't have that much footage, so it seems to have gone by more quickly," says Eagleman.
This might suggest that we can stretch our lifetimes by trying to pack as many different and exhilarating experiences into it as possible. The trouble is just finding the time."http://www.newscientist.com/article/mg21128330.800-about-time-does-it-really-fly-when-youre-having-fun.html
