Speaking to, Mary McGrath from Barrack Street, cited a stress-free mindset as her best life advice.
"I never worried and so long as I was working I couldn’t care less," she said.
At the age of just 16, Mary started work at the Jennings Soda Water Factory, making sauces and lemonade - a job she stayed in for over 30 years.
"It was tough work, but I enjoyed it," she said.
Despite the current challenges of the pandemic, Mary's loved ones ensured she celebrated her birthday in style with a 'physically distant' birthday party outside her house today.
Family, friends and neighbours joined the Lord Mayor of Cork, Cllr John Sheehan and the Lady Mayoress, Aedamar Sheehan to celebrate the occasion.
The party was organised by her friends at South Parish Old Folks Club, her nephew, Danny, her niece Geraldine Brosnan and by Ballyphehane Day Care and Ballyphehane/Togher Community Development Programme which she regularly attends and describes as 'the club'.
A previously planned birthday celebration was postponed due to the Covid-19 restrictions but Mary didn't want it postponed any further so it took place today.
Mary said she also attributes her health and longevity to having wonderful friends.
"I've always had lots of friends and lots of friends from different backgrounds.
"I'm part of the Ballyphehane Friendship Group and take part in the community education classes at the Day Care Centre where we have art, music and get to meet with lots of younger people too," she said.
"I just enjoy people and like to stay connected with people.
"I would have loved to have invited everyone into the house for a cup of tea after the celebration today," she said.
Wishing her a happy birthday on behalf of the citizens of Cork, the Lord Mayor said it was an honour to attend the celebrations.
"Mary has long been at the heart of her local community and at the heart of activities in the community and is loved by young and old in that area. She really is a local legend.
"Community spirit has burned bright in recent weeks and it's fantastic to physically watch a community rally around and celebrate one of their older neighbours," he said.
Richard T Cooke of the South Parish Old Folks Club, who performed one of Mary's favourite songs, 'Up the Coal Quay', at her birthday party, praised Mary's charisma and exceptional character.
"Mary is a member of South Parish Old Folks Club for over 50 years and she has been an inspiration to all of us – she’s like the Queen Mother!"
Mary played a major role in the very popular singing group: 'The Swinging 60s Choir'.
For almost 20 years Mary and the choir performed in local festivals, community events, community centres, hospitals and retirement homes.
The group also recorded a song titled 'The Over 60s Song - It’s Great To Up And About' for Paddy O’Brien, activist for the elderly and founder of the Over 60s Talent Competition.
Wishing her a very happy birthday, Mr O'Brien praised Mary's "wonderful outlook on life".
"Mary is an exceptional lady. Her years have gone on but Mary never got old.
"She has a great positive mindset and is an example for all elderly people.
"Mary never married, she told me that she was always happy in her own company," he said.
At the age of 104, Mary still lives independently.
