"How far can you walk without having chest pain or shortness of breath?"
"I don't know."
"You don't know?"
"I drive everywhere."
"But I mean, like, from the parking lot to the store?"
"My wife drops me off in front."
"But if you needed to walk, can you walk a block?"
"Why would I have to walk a block? My wife drops me off."
"Can you walk across a shopping mall?"
"I use a golf cart."
"But can you walk, if you have to?"
"I have no idea."
"Aren't you curious how far you are able to walk?"
"No, I don't want to walk. I drive."
"But you want to be able to walk."
"You don't care if you can walk?"
"Like I said, I don't need to walk."
"In your house, can you walk without getting short of breath?"
"I live in an apartment."
"But you can walk to, say, the bathroom."
"It's three steps from the couch to the bathroom, and three steps from the bathroom to the kitchen."
"And you can walk those three steps without getting short of breath?"
"You guess, or yes?"
"I don't know. Usually my wife brings me my food."
"Do you have to walk down the hall in your building?"
"We're right next to the elevator."
"Do you walk in the grocery store?"
"My wife does the shopping."
"You literally don't ever walk more than a handful of steps at a time, ever?"
"That's what I've been trying to tell you."
"I think I'm going to have you walk down the hall."
"I'm really tired today. I'd rather not."
