We?ve all been there. Just why are these pesky houseflies so hard to swat?

The answer might lie in the way they see the world and sense time.

Trying to swat a fly is like trying to shoot Keanu Reeves in The Matrix because time appears to move more slowly in the minds of smaller animals, a new study has claimed.

The ultra-nimble fly is capable of processing nearly seven times as much information in a second as a human. This means a rolled-up piece of newspaper that is moving so fast that it appears as a blur to our eyes is, to the fly, more like the slow-motion bullets that are easily dodged by Neo, Reeves? character in The Matrix.
