This is a very useful device.
You can hang on to it and drag yourself around in bed.
They can hang transfusions and drips and stuff off it.
And you can use it quite effectively to confuse the wardens.
Wait until you hear them lurking around in the corridor with their instruments of torture, do a quick 30 pull-ups and your blood pressure shoots way up.
Your pulse is over 100, too
You’ve never seen them run for a doctor so fast….
