what animal is lazy other than humans
In the article above, it basically covers how a lot of the animals we associate with industriousness (like beavers and bees) actually spend most of their time just doing nothing. You go and do field work on some species, and most of your time will be spent just watching them sitting there motionless. Being lazy helps conserve energy, so that when it is truly needed (like in a fight-or-flight situation) it is available for use.
