“Researchers at the Wolf Science Center and the University of Veterinary Medicine, Vienna, set out to determine if the howl of a wolf is an involuntary cry caused by stress or a conscious result of separation from a companion that is particularly important, either because of social rank within the pack or genuine affection for a preferred mate.
The wolves howled the most when they had a special relationship with the missing member of the pack. The level of anxiety caused by the separation, as determined by measurements of the stress hormone cortisol in the wolves’ saliva, had virtually no effect on the howling. That indicates it was friendship, not anxiety, that caused the ruckus.”

Do as the wolf does. You owe it to yourself to live as a free spirit. The past is over. And we’re just moving forward.
