nature's way of saying 'wake me when the buffet reopens.'
means a state of drastically slowed metabolism some animals enter to survive a season with no food, by sleeping through it.
from from latin hibernare, 'to pass the winter,' rooted in hiems, winter — the same root that gives us hibernal and, distantly, the name of the season itself in romance languages.
