I was 17 and working in a relatively posh job - County Court Clerk - and hating it. I used to go up to the attic which we called the archives, where all the old ledgers were stored, supposedly to do some filing, and read those 19th century court records, all written in copperplate. Then I'd climb on a pile of them to look out of the big semi-circular window over the Calder Valley, full of terrace houses, mills and mill chimneys spouting black smoke, and try to imagine the place in prehistoric times.
Then someone would come up and drag me back to reality, and work.
One day I discovered I had no energy - it got worse, I made a mess of everything, got shouted at all the time, finally went to the doctors and ended up in hospital. I had severe anaemia from heavy periods, a cyst on my cervix and other problems. I learned a lot in the week in the women's surgical ward, and have been a feminist ever since. The lives of some women - awful!
Yes, 50 years ago was quite a turning point for me.
