Most mammals hibernate in some way. Hibernation is a state of inactivity
and metabolic depression (bears can lose forty percent of their body weight
during the winter by sleeping). What’s your Hibernation Inducement Trigger?

Sleep, ignorant of pain,
sleep, ignorant of grief,
may you come to us blowing softly,
kindly, kindly come king
.”
Quotation from Sophocles, Philoctetes
