TRACEY Moore might be 53 with five grandkids, but she's no nanna.
The personal trainer drives a V8, says things like "oh snap" and enjoys jumping out of planes.
That's why she was so shocked to find out the term "senior" referred to anyone over the age of 50 when she was asked to take a "seniors" class.
She wants the community to think long and hard about what it means to be senior and realise that turning 50 isn't the start of old age because she says "50 is the new 30".
"I was offended," Ms Moore said. "I was expecting people (in the class) well into their 60s or 70s.
"I wish I had a mirror to see what my face looked like when (the client) told me it was over 50s. I thought well I am over 50 and I'm definitely not senior."
In Australia people are expected to live into their 80s, the official retirement age is 67 and to claim a senior's card or the pension you have to be 65. "I am champing at the bit to get this out there in the public," Ms Moore said.
"It's ridiculous really, are we going to be seniors for 20 years?
"They've put the retirement age up, life expectancy is up, but what we think of as senior's age isn't reflecting that.
"If we don't talk about this nothing will change."
Business owner Sharene Tramacchi spends her days working out or redesigning homes - it's a hobby.
She's just installed a trendy graffiti wall in her bathroom, too. She says age is just a number.
The friends agree classifying people in their 50s as senior can be detrimental.
"When I think of seniors I think of people who can't do everything for themselves," Sharene said.
"That's not me.

"If you talk about people in their 50s as being senior then they will start to think they're too old to do certain things when that's not the case."
So what's the secret to being as active and vibrant as these women when you're 50?
It's no surprise high school P&E teacher Denise Marrable agrees with personal trainer Tracey Moore in saying the answer is exercise.
Ms Marrable can "run rings around her students" who don't believe her when she tells them how old she is.
"It's not about looks though," Ms Marrable said.
"I don't want to work hard all my life only to retire and realise that I can't do all the things I want to do like go travelling."
