Health is everywhere, which is one reason why being a health librarian is so appealing and compelling.
I made a journey through a particular part of my home city. At one end of the journey, shop staff were talking to each other about people they had observed through the window. There was a man who was having what might have been a fit, who then refused the ambulance that the shop staff called for him. There was another who tripped and fell on the tramlines. And there was someone who had fallen from their bike on the tramlines. If this has happened to you in Sheffield, you should put the details on this website.
And at the other end of the journey there was a parent and children walking, with the parent explaining to their children something about the health of a grandparent and how it was affecting them.
