At the age of 67, David Reddin decided it was time for a change; time to break from his corporate past, time to try something new.
The thought came to him while he was working out his contract as a consultant, and was weighing up whether he was really ready to retire.
An avid outdoors walker, Reddin decided to turn a spare-time passion into a full-time career, and co-founded a walking tours company Walking Holidays.
"Creating the business, building the website and social channels has kept me very busy and I'm loving every minute," he said.
"The joy that comes from stretching myself physically and mentally, and feeling that fulfilment at the end of the day is great ... and of course, going on the trips is the best part."
Ambitious career shifts are often associated with younger workers, who appear to be perpetually on the lookout for new opportunities and have all but abandoned the belief in having a job for life.
But new research suggests that workers' hunger for change crosses the generational gaps.
According to a study of 6000 people by Lonergan Research, half of all workers aged over 50 would change their career tomorrow if the right opportunity arose.
Insurer Apia, which commissioned the research, said the findings demonstrated that growing older "doesn't result in complacency" and the hunger for personal and professional satisfaction is strong at any age.
"Today's over-50s are not over the hill," Apia's Geoff Keogh said.
"Growing older ... means freedom and the luxury of time to accomplish great things – arguably [over 50] is the stage in one's life where the possibilities are actually endless."
The new study also suggested that career change is "not necessarily confined by the next office job", with 77 per cent of respondents over 50 saying they believed creativity increases or stays the same with age, and many were interested in starting their own businesses.
Mr Keogh said the study showed many over-50s were prepared to make brave, life-changing decisions about their futures, and career switches were "not exclusive to the millennial".
"As we live life, we gain the knowledge, resources and confidence required to achieve our goals," he said.
