Hands are tricky things. You might assume that they are entirely on the side of virtue, reaching for sustenance from the supermarket shelves, tapping out serviceable prose on the keyboard, soothing a fevered child’s forehead or stroking a lover’s back.
But that’s only when they’re obeying orders which, it turns out, isn’t often. Left to their own devices, hands ceaselessly return to the body’s surface, where they make all sorts of moral and social mischief – plucking at scabs, picking at noses, straying towards the genitals for a comfort fumble. It’s for that reason, says author Darian Leader, that we spend so much time playing with our mobile phones in public: continuously swiping at a screen in the company of others is just about acceptable, playing pocket billiards really isn’t.
