Hundreds of people are alive and well thanks to Mrs Webb's generosity and dedication to making regular blood donations with the Australian Red Cross Blood Service.

As it stands, Mrs Webb has donated blood 101 times and 99 of those donations were made in the Highlands.

"I started donating in probably 1977 or 1978," she said.

"People from my workplace were going so I thought I'd go too, and I'm still going."

This week will mark 71-year-old Veronica's 102nd donation, a remarkable achievement that the Mittagong woman was very humble about.

"It's such a little thing to give, and really, I get more back myself."

Mrs Webb said the donations were a nice way to get some "me time".

Between working part-time, looking after her children and doing her husband's book work, Mrs Webb said she didn't get much time to herself.

"I wouldn't have had the time to sit at home and just read, this way I was doing some good and I got to relax for at least 20 minutes," she said.

"They check your blood pressure while you're there, so I can keep an eye on that when I make my donations every three months."

For anyone who has a donation on their to-do list but hasn't had time, Mrs Webb had some helpful advice.

"There's nothing to be afraid of, it's just a bit of a pin prick and the actual donation only takes maybe five or 10 minutes," she said.

"The nurses are all very efficient and very cheerful."

Mrs Webb urged anyone who was healthy and feeling well to take an hour at the most to help someone.

"Now that it's in the mobile blood bank you can make an appointment online and there's hardly any wait time when you arrive," she said.

Red Cross Blood Service spokesperson Jarrod Flynn said a blood donation was helpful to more than just the individual that would receive it.

"A donation of blood has a ripple effect, from the person receiving the blood, right through to their family and their friends," he said.

"Blood donors help save the family and friends of patients needing blood from the inconceivable prospect of losing a loved one."

Mrs Webb said she would keep making donations as long as she was well and "for as long as they'll have me".

"I just think if I can help someone that's good - it certainly isn't hurting me."

The Red Cross Blood Service will be in its new location at Bowral Swimming Centre on the corner of Mittagong Road and Oxley Drive from today until Friday.
