Imagine a Lion is stalking a Zebra then launching into a sprint to attack! The Zebra, startled - responds with a frantic sprint to escape. The Lion, unsuccessful on the first attack-lunge, quickly stops to rest and recover. The Zebra, now with an apparent opportunity to escape - stops and rests as well! They both know that ‘intermittent-action’ is more efficient. Also: neither the predator (here the lion) nor prey (here the zebra) exist in isolation... the predator could find other ‘opportunities’ whilst surveying the landscape in the intermittent rest period. Plus the prey is continuously ‘threatened’ by multiple predators - so simply over-expending energy to escape one predator could leave them over-vulnerable to other potential predators!
- enjoy little burst of activity
- give it some oomph
- go on! get moving
