"I always go by what my mother used to say. They can talk about all the diets they like, but the best diet of the lot is a little bit of everything, but not too much of anything.
"I think that's quite a good motto.''
Mrs Gunn celebrated her birthday yesterday at a packed Millers Flat Hall with 130 family members and friends.
Mrs Gunn was born Hetty Orr in a family of eight children in Millers Flat on June 26, 1916.
She remembers a time before electricity came to the area.
"I was 12 when it came on. I was just waiting and on came the light.
"We were allowed one light and one plug.''
She married Coal Creek farmer Bill Gunn in 1938 and lived with him there on a sheep and cattle farm.
"It was a happy marriage. I think the secret of a good marriage is to share.''
She would feed the farm workers who stayed at the house, and look after her five children.
"I worked very hard, but I didn't go out to work; I worked at home. There's plenty to do on a farm.''
Mrs Gunn experienced life with kerosene lamps once again when the couple moved to buildings on another part of the farm in Shingle Creek, which left them without electricity for eight years.
"It would have cost £200 to bring the electricity down, and we didn't have £200.''
Family was a very important part of life, she said.
"I would always be home with the kids. I think that's lacking these days.''
She loved spending her days gardening.
"We always had a vegetable garden. Bill would do the digging mostly, but I did all the rest of it.''
The two retired to a house in Roxburgh in 1979.
Mr Gunn died in 1999 at the age of 88. Mrs Gunn lived in the house until last October.
Since then she has alternated between her three daughters' houses, all in the valley.
"It's five weeks at a time, so we don't get sick of each other.''
Longevity runs in Mrs Gunn's family.
Two of her older brothers lived until they were 96.
She was never a smoker or big drinker, she said.
As well as her five children, she has 19 grandchildren, 34 great-grandchildren and 4 great-great-grandchildren.
Daughter Joan Rowley said her mother was in very good health for her age.
"Her memory is great. Probably better than mine. She's still our mum.''
Mrs Gunn said these days she knits and helps with housework.
"I've done as much as I can as long as I could.''
