This Earth That Holds Me Fast Will Find Me Breath
The Morgan Freeman story
Every so often he grabs his left shoulder and winces. It hurts when he walks, when he sits still, when he rises from his couch, and when he missteps in a damp meadow. More than hurts. It seems a kind of agony, though he never mentions it. There are times when he cannot help but show this, the fallout from a car accident four years ago, in which the car he was driving flipped and rolled, leaving Freeman and a friend to be pulled from the car using the Jaws of Life. Despite surgery to repair nerve damage, he was stuck with a useless left hand. It is stiffly gripped by a compression glove most of the time to ensure that blood doesn't pool there. It is a clamp, his pain, an icy shot up a relatively useless limb. He doesn't like to show it, but there are times when he cannot help but lose himself to a world-ending grimace. It's such a large gesture, so outside the general demeanor of the man, that it feels as if he's acting.
"It's the fibromyalgia," he says when asked. "Up and down the arm. That's where it gets so bad. Excruciating."
