Light switch - switch on
Let’s try, every day
A check - a brief check,
To keep function and form

Stretch the knee to the chest,
Pull in close, and away -
Keep the motion in motion
From the day you are born

Deep in your sternum
Lies tight little fear
That the light may not light
That the knee bends no more

But don’t look away
Do try it again
Every day,
Every day -
It is what we are for
