Laziness or Sloth is the disinclination to use energy and is seen as a negative trait in most cultures. Being lazy has also been associated with being a slacker, or a good-for-nothing person wasting time.
New scientific research tells a completely different story and lists out many advantages of being a couch potato. Being tactically lazy can actually be good for us.
Humans may be seeing laziness upside down, as it may not really be a sign of inefficiency or unproductivity, but a result of being able to work smartly and free up time to do nothing. Sitting lazily can also trigger further smart work.
