At 100 years old, Barbara McDonald was keeping The Recorder guessing.
Amid the music and cheers at her birthday party at Hammill House on Friday, she was asked to reveal the secret to reaching her milestone.
"I have no secret," she said with a gleam in her eye. "But I never drank of smoked."
Clues to the love-enchanted life of the super-nan centenarian came from her son Robert McDonald.
"She lived in Three Chain Road for 75 years. Our Dad Frank was a fitter in the smelter and died early after 29 years of marriage and she never remarried," he said.
"She has been a good mum. Pam Harmer and Jenny Cagney, who are here today, lived on either side of Mum's house and developed a special relationship with her as their second mum.
"Mum cared for children for a number of years for working mums.
"She was in the Anglican Church Mothers' Union for 50 years."
Mrs McDonald was born in Port Adelaide and remains a Magpies' fan.
Asked to reveal the greatest thing that happened in her life, she replied: "I got married and left home."
She has five grandchildren and 11 great-grandchildren.
Woolworths supplied the birthday cake, Coles served some afternoon tea, Trend Party Palace provided half-priced balloons and Butterfly Kisses/Joy to Independency gave flowers.
