Bears Priming their Fascia???

The new Planet Earth 2 Series has some amazing footage of Bears ostensibly scratching their backs on trees.  The narrator states this is to help remove their winter fur coats.  Hmmm...  Looks an awful lot to me like some of the morning fascial priming moves!  Scratching the skin...rubbing...massage...brushing...pushing the fascial layers against something..smushing and shear the layers are all ways of waking up the sensory nerves in the fascia...10x more sensory nerves in the fascia than in the muscles!

Maybe this is part of their way to wake up their body after hibernation?  Now he is all facially primed and ready to work and play in life!
