Asked if she would be interested in playing someone with Alzheimer's in the Dannevirke Theatre Company's production of The Old People Are Revolting, Janis agreed to give it a go.
"I really loved being in the show because I think director Gary Mitchelmore had selected a cast well-suited to their roles. Mind you, I did think I was past all that stuff. However Gary was a very, very good director; patient, kind and he didn't push."
Struggling with dyslexia, Janis had to be creative when it came to learning her lines.
"Things can get a bit jumbled so to help learn my lines [I] recorded them on my cellphone and constantly played them while I was busy at my weaving loom."
Janis said she enjoyed the experience though at times felt extremely tired: "But once I got to the theatre I'd revive and I'd be on a high. I celebrated my 80th birthday at a matinee performance and my sister brought along a cake, my son, John, came from Taradale and a friend from Picton.
"You know, if you take the zero away, then I'm only 8, with a lot of living to do yet."
Although now on her own, with her little dog Gilly for company, having battled breast cancer and a serious heart condition, Janis has never been happier.
"So long as you're happy, healthy and have friends, nothing else matters."
And will Old People Are Revolting be her stage swansong?
"I won't say no because you're closing the door," she said. "I don't know what's going to happen in my life ... that's what makes life exciting. I love it here in Dannevirke, where the people are kind and supportive."
Janis is an accomplished painter who spins, weaves and carves stone and wood.
Although she doesn't know where her love of theatre came from, it also seems it runs in the blood of her son, John, who had arole in the Tararua Theatre Company's production of Fiddler on the Roof in Dannevirke in 2011 as the butcher.
"I didn't know he could sing like that," she said. "My daughter, Anne Johal, is very creative too and runs the Talking Cat Art Studio in Hastings."
