You're not dying...

Diane Arbus: 

What is it?

Lionel Sweeney: 

Well, every month or so I'm able to breathe about five percent less. My lungs are disintegrating. It's getting harder and harder for me to breathe... deeply. In a matter of months, I'll drown without even swimming, because there'll be nothing left... of my lungs.

Diane Arbus: 

You're not dying.

Lionel Sweeney: 

Yes, I am.

Diane Arbus: 

No, you're not.
