"Some animals are lightning fast. Others are pitifully slow. But slow and fast are relative terms. Four miles per hour doesn't feel very fast to a human: it's approximately one body-length per second. But to a small insect it's approximately 100 body-lengths per second. A human traveling that fast would be going 20,000 miles per hour! This is why some animals' brains process visual stimuli much faster than ours, and why they have better reflexes (think about how hard it is to swat a fly). What does it feel like to comprehend the world at such speeds?" -- Alex Reisner, creator of SpeedOfAnimals.com
