Debbie Preece, 28, cannot imagine that she would ever want to retire from teaching.
She said: "At the moment I love what I'm doing and it is my life.I've known teachers who wanted to carry on and others who have gone part-time or done supply."
But Miss Preece, who teaches reception and Year 1 pupils at St Laurence primary, in Ludlow, said it is having a choice that is important.
"Being able to retire at 60 is a good thing," she said.
"I'm not sure that I want to carry on until 65 and it is a relief to know that once you get to 60, if you want to retire, it is an option."
