Ms Gwennap trained as a student nurse in Essex and went on to work as a healthcare assistant at West Cornwall Hospital in Penzance before working as a children’s nurse, where she met her husband in 1998.
She said a friend filled out an application form for her to do the training.
“My friend wanted to do her training and the first I knew about it was when I had a letter to say I had been accepted for an interview,” she said.
“I think the most wonderful thing about it was working in an area where I actually knew a lot of the people I was looking after.
“It seemed like a good thing to do because I was helping friends and people that I knew.
“I loved every minute of it, it fitted me, and I enjoyed it so much.”
Reflecting on her 50 years of service with the NHS, she said: “It’s just gone in the blink of an eye.”
