I am thrilled that European beavers are being reintroduced to the UK some 500 years after being hunted to extinction.  It is wonderful.  That was all the newspaper had to say.  Instead...

The beaver was hunted to extinction for its fur and the pain-relieving properties of its anal gland secretions.

(Emphasis mine.)

Okay, now I am officially disturbed.  Exactly HOW did ancient Brits figure out that beaver anal secretions had pain relieving properties?

Ugh.  Forget I asked that....
