Ten years ago today I was working in a hospital, cleaning up and finishing off domestic work. I hadn't started medical school at that point, and it was summer break from university.
The news said that there had been power surges all over the underground in London, and that further news would be updated.
It was the day after the UK had won the bid for the Olympic Games for 2012.
I didn't think a great deal of it at the time. I carried on working, along with other staff.
Only as the morning went on, did we hear more about what had really happened.
I remember being horrified at what we were hearing; co-ordinated terror attacks on public transport.
My thoughts are with the families of those who died, and the survivors who are reliving it today.
