This is the scientific reason the fly is hard to beat

Flies do like to fly around humans. Undoubtedly, it is very disturbing. Things may be done to get rid of her like a hit. but who would have thought, the fly would move first before the blow came, how did it happen?

That's because how animals see the world. Flies are small animals, but they see the world slower than others or called slow motion. It is like looking at a second hand on the clock. If humans see the clock turn of the clock is 1 second then the fly will see it 0.25 seconds. The human eye ratio can only see 60 frames per second and flies can see 250 frames per second.

Prof. Roger Hardie from the University of Cambridge who studied flies found that the creature's eyebrows are so fast, that flies can blink up to 400 times per second. That can rival the view of the supenya or often called the killer fly.

This indicates that the fly almost can not be touched if he sees the danger that comes. Great is not it!
