This is Fresh Air. I'm Terry Gross. Is there anyone who doesn't know who Harrison Ford is?

Probably not, not after starring in the original and the sequels of Star Wars, the Indiana

Jones movies, and Blade Runner. He's in his 80s, but in the last three years you might have

seen him in the final Indiana Jones film, The Dial of Destiny, the

prequel to Yellowstone called 1923, and his current series, Shrinking. Three seasons of shrinking

are streaming on Apple TV, and it's been renewed for a fourth. He plays a therapist, Paul,

who heads a practice that includes two other therapists, Jimmy,

played by Jason Siegel, and Gabby played by Jessica Williams. Paul is at an age where most people

have retired, but he doesn't want to. At the same time, he thinks maybe he needs to. He has

Parkinson's disease. At first, the symptoms were relatively minor, but they've progressed.

His hands shake so much it's difficult to put the toothpaste onto the toothbrush.

Even more problematic because it affects his work, his shaky hands are making it difficult

to take notes when he's talking with patients. Michael J. Fox is in a couple of episodes,

playing a man who has a more advanced case of

Parkinson's and is very depressed. They first meet at a doctor's office where they're both patients.

Paul is a gifted therapist, but it's hard for him to express emotion and he has a dark and cynical

sense of humor. In this scene from the current season, season three, Paul has

returned to work after taking some time off because the UTI was causing hallucinations. So this

scene is from his first day back at work. He's telling Jimmy he thinks it might be time to retire.

In the past, Paul had asked Jimmy to tell him when he thought it was time.

Now Jason Siegel's character, Jimmy, speaks first.

Hey, how's your first day back?
