At least as far as the NSW Electoral Commission is concerned, the oldest person on earth (in fact, the oldest person in history) is 124 years old, living in Dungog, and so energetic in their venerable years that they're running for council election in September.
To put that in perspective, the last person to hold the title of oldest living human was 117-year-old American-born Spaniard Maria Branyas Morera, who credited her advanced longevity to "staying away from toxic people".
