Better uses for your thumb

Signalling OK;

Releasing a muscle knot;

Clicking a Bic;

Measuring the distance between your big toe
and the end of a new shoe;

Opening a CD case;

Identifying yourself;

Pulling a plum from a pie;

Pressing your closed eyelids against your eyes
until you see stars—

anything but galloping
across the endless wasteland
of social network updates.
