Why Are Sloths So Slow?

Have you ever stopped to wonder just why sloths are so slow?

Sloths spend most of their time eating, resting, or sleeping; in fact, they descend from their treetops canopies just once a week, for a bathroom break.

How can these creatures possible operate on such a pace?

Kenny Coogan describes the physical and behavioural adaptations that allow sloths to be so slow.
