DONATING plasma runs in the veins of Paul Kirkpatrick.
When he was seven years-old, he looked on as his grandmother worked as a superintendent at the Red Cross.
"My grandmother explained to me how it was a life-saving procedure," Mr Kirkpatrick said.
In 2014, he surpassed 150 donations to the Australian Red Cross Blood Service since his first donation as an 18 year-old.
Mr Kirkpatrick said it had become part of his fortnightly routine.
"I'm semi-retired now so I factored in that I could easily be able to donate every fortnight," he said.
"After a while, scar tissue builds up so you don't feel it after about 20 times.
"You just need to make sure you're well-hydrated beforehand."
Mr Kirkpatrick's tally sat at 165 on Sunday as he attended a Red Cross event in Bendigo celebrating the dedication of local milestone donors.
He will make it 166 donation today as he attends the Bendigo Blood Donor Centre to give more plasma, with the potential to save another three lives.
