If there's one thing koalas are good at, it's sleeping. For a long time many scientists suspected that koalas were so lethargic because the compounds in eucalyptus leaves kept the cute little animals in a drugged -out state. But more recent research has shown that the leaves are simply so low in nutrients that koalas have almost no energy. Therefore they tend to move as little as possible-and when they do move, they often look as though they're in slow motion. They rest sixteen to eighteen hours a day and spend most of that unconscious. In fact, koalas spend little time thinking; their brains actually appear to have shrunk over the last few centuries. The koala is the only known animal whose brain only fills half of its skull.

 

 

Trying to produce everything yourself would mean you are using your time and resources to produce many things for which you are a high-cost provider. This would translate into lower production and income. For example, even though most doctors might be good at record keeping and arranging appointments, it is generally in their interest to hire someone to perform these services. The time doctors use to keep records is time they could have spent seeing patients. Because the time spent with their patients is worth a lot, the opportunity cost of record keeping for doctors will be high. Thus, doctors will almost always find it advantageous to hire someone else to keep and manage their records. Moreover, when the doctor specializes in the provision of physician services and hires someone who has a comparative advantage in record keeping, costs will be lower and joint output larger than would otherwise be achievable.
