This particular pride of lions at the Phinda Game Reserve in South Africa had a set of young cubs along with some cousins that were about a year older. As the adults slept, the younger cubs were in a constant state of motion - running, fighting playing - until they passed out from exhaustion. They never stopped for long. It was almost like they were afraid they would be missing out on something if they were asleep. #southafrica @natgeocreative
