Whoydensday: Ace (Guest Post from Chally)

I don’t believe you’ve met my young friend Ace, an expert in calorification, incineration, carbonization, and inflammation.
-The Doctor, The Happiness Patrol

Dorothy McShane of Perivale, UK, better known as Ace, was the Doctor’s companion in Doctor Who from 1987 until the show’s cancellation in 1989. She was young. She was independent. She was tough. She was smart. She was a glorious feminist character.

Contagious yawning and canine empathy

From the BBC:

Until recently it was thought that only humans and their primate cousins displayed contagious yawning, but now it’s been shown that dogs display the behaviour as well.

Yawning, although sometimes a response to extreme stress, is more often a sign of tiredness; but the reason for why yawning is catching is not fully understood.
