Feeling stressed? Watch this.

I don't think I've ever heard anything narrated in such a calmly and deliciously articulate way, even if the owner of the voice is talking about possible sheep-death caused by brambles . . .
I came across this while researching a plant that ensnares sheep in Peru - I had imagined a triffid-like bit of flora that lances out a green spiny limb and drags the unfortunate animal into a gaping mouth but actually it's similar to the bramble bush in that wool-clad animals will wander while feeding into a patch of the thorny plants and become entangled.  Any further wriggling to get free will make it more captive until . . . well, the end, sadly, through starvation or bird attack, etc.
A clever bit of evolution - a sheep-sized bag of ready made fertiliser at the foot of the plant. Ugh.
