I lived in Blackpool for the first 26 years of my life then moved inland to East Lancs where I have been ever since. My on-line records go right back to when I had my baby vaccinations in 1948 just after the NHS was born, it includes brief details of my broken tibula and fibula in 1952, chicken pox in 1952, measles in 1953 and then jumps to 1976 shortly before I moved. All these were well before computerisation, so I assume my paper files were transferred and someone went to the trouble of entering them on the system. All very fascinating.
