Dodging Bullets

Vision is a powerful sense, but does it have the power to stop time? Recent research indicates that time moves at a slower rate for some creatures.

If you’re a fly, you can process close to seven times as much info in a second as a human, which is why houseflies split their sides over our attempts to swat them – they see us coming in slow mo.

If you’re a dog you can process information at twice the rate of human, which is why TV is of little interest. A flickering image is all dogs see. If you’re a leatherback turtle on the other hand, time flies. Those guys get roughly a third of the information that we do in a second. It seems that perception of time has to do with size and metabolic rate. Perhaps nature is nodding to the little guys. Now, how to be as fast as a fly and laid back as a turtle?
