Today's smile question and goal: Have you been getting enough sleep? If not, go to sleep early tonight! Additional fun info: Humans, domesticated dogs, lab rats, and chimpanzees have all been documented to contagiously yawn. The budgies, though, have been the first non-mammal to exhibit this behaviour. The form of empathy would be considered primitive or seen as mimicry.
