I can slightly move the “useless” muscle that lets some people wiggle their ears. Of more interest is that I feel the muscle slightly twitch when someone/something approaches outside of my visual field. It feels almost like a sixth sense, but obviously it is linked to my auditory system picking up a sound I don’t appear to actually hear and making my auricular muscles twitch – a bit like a dog “pricking” its ears up. Perhaps it’s not such a useless muscle after all (8 February, p 19).
