While not everything is true in fiction – hence the word – writing is based on what I know. It’s a guessing game. The following is the first draft of a dialogue from The Ark:
“I ruined my knee when I was a kid, skiing in Vermont, torn acl, mcl, everything. I had arthritis after that. No cartilage, 15%, something like that. It was just bone on bone. I had to have a replacement.” 
“You didn’t have the surgery?”
“No.” He thrust his hands back and forth in front of him, miming. “I did the elliptical instead.”
“What’s that?”
“The machine. I worked out every day and took cartilage pills.” He ate the rest of the meat. “It’s fine now. Still. No running though. I can only dream about that.”
“You were afraid you’d die?”
“I don’t know about that. I don’t know. I remember the feeling as a kid, when I had the first surgery. I woke up cold. They had monitors attached to my chest. I wasn’t going to surrender just because they said I should.”
“I broke my hand. They put me out before I knew it.”
“You have to sign.”
“It was in Newfoundland.”
He tore off another strip. “It’s probably better like that.”
I did ruin my knee in my younger days and use the elliptical daily; however I’ve never backed out of a surgery, skied in Vermont nor eaten seal meat…as of yet.
