Sure. That is until you are on the wrong side of 40, your back aches, your feet hurt and you have a dodgy knee.
Not for Carolyn Grey that tired set of excuses. The 56-year-old Hamilton grandmother does not have time to sit and whine.
The former international is too busy muscling up on the low post for the Waikato Wizards at the women's basketball championships in Dunedin this week.
"To me, age is nothing," Grey said.
She has been playing top-level basketball for more than 30 years and still cuts an imposing figure on court, moving with a grace that belies her age.
And if she had the odd ache after two solid days of basketball, she was not about to let on.
"Fantastic," was her response when asked how her body was holding up.
"I wake up every morning and am very thankful for my eternal youth and endless energy."
Amazingly, Grey has avoided major injury and hopes to continue playing in her 60s.
"I believe I'm going to feel like this when I'm 60. I feel just as competitive as ever."
Some of her opponents are 40 years younger, but the generation gap is not something Grey thinks about. She is just happy to be doing what she loves. That is what has kept her involved for so long.
"Most of it is just passion and I'm very driven. And, I guess, I work in the fitness industry and you are around healthy people which helps."
Grey owns a gym in Hamilton which specialises in helping women reach their fitness goals. She is happy to be a role model and help inspire women to stay active.
On the court, though, Grey wants to inspire people with her skills and prefers her age remains out of the equation.
"I get a lot confidence knowing that my team-mates have faith in my ability."
