Without that change, it would not have been possible for me to become a teacher. It's about the only thing I can think of to thank this Government for.
Having raised five children of my own and seen them marry and have children, I experienced something of an "empty nest" syndrome. I had left school without any qualifications in the 1960s and back then it was OK to get married and have children in your teens, a thought that would horrify today's generation.
To help my dyslexic daughter obtain her GCSEs, I went to night school with her to take English GCSE.
This spurred me on to further success. I continued with GCSEs and then A-levels. What next? A degree. I was already a grandmother, still working part-time. Was I mad? Well, yes.
I applied to Reading University, which offered me a place to read English literature part-time. It took me six years, but I did it. I just loved learning and being in that environment.
Could I possibly combine my love of education with my love of children?
Again, Reading University offered me a place on its graduate teacher programme. I qualified in July last year, just three months short of getting my pension.
I now teach in a local primary school and I'm in heaven. It is the best job. With the experience of age and family I feel I have a lot to offer: patience, time and understanding.
And with no ties, relationship, children or money worries, I can devote all my energies to my wonderful new profession. So to any OAPs out there, just let me say you are never too old.
Just when my family thought I was going to put my feet up in a pair of tartan slippers with bobbles on, I started a whole new career. Teaching is simply the best, go and find out for yourselves
