Archer Brady has 65 roses.
He will carry each with him all his life, unless a cure is found. Masking the seriousness of his condition, '65 roses' is rhyming slang for 'cystic fibrosis'.
The disease the four-year-old Junee boy was born with means Archer's lung and pancreatic health sits on a perpetual see-saw.
"CF lungs are not built the same way as those without CF, and if Archer gets a common cold, or worse a cough, this can lead to him becoming very ill," said his mother, Bianca.
With each meal, Archer takes enzymes to help his pancreas absorb food. He is aware of his condition, but aside from his mealtime ritual, he is a normal four-year-old.
"Archer keeps very active and especially enjoys swimming [and] riding. He thoroughly enjoys active outdoor play," Mrs Brady said.
Three days a week, Archer attends Junee RSL Memorial Preschool, and on Thursday, his 50 fellow students participated in Crazy Hair Day to raise funds for cystic fibrosis research.
"Whatever we can raise will help in finding that cure, but for us it's more about awareness," said preschool director Rebecca Hart.
Research advancing every day children like Archer may be able to one day surpass their low life expectations.
"The hope is that by the time Archer is 37, there will be an answer, and he'll be abler to continue living his normal life," Ms Hart said.
The youngest of four children, when Archer arrived at the preschool there was a moment of anxiety.
So serious is his condition that a regular day could easily turn to catastrophe for the preschool.
"We have to be careful and let the kids and parents know that what's a cold to one child could mean hospitalisation for Archer," Ms Hart said.
Each educator has completed CF-Smart training to be able to address his needs and respond in a crisis.
"His mother does an amazing job, and just absolute hats off to her," Ms Hart said.
"Just looking into the room, you would never know he was so seriously ill because his family have made sure he can live a normal life."
The Cystic Fibrosis Foundation estimates that one in 25 people unknowingly carry the CF-gene.
By those odds, at least one other person in Archer's class holds the gene.
Being unaffected themselves, its reality may only manifest in a child who is born of two parents with the matching defect.
