I used to live just round the corner, and both my children were born there.

Coincidentally, Dr Josep Trueta, after whom it's named, went into exile in Britain after the Civil War, taking up an academic position in Oxford, where he developed specific triage techniques based on his frontline wartime experience in Spain, which were then used by Allied medical staff in WW2.

And what is triage if not, in a way, the car park entrance barrier of the field hospital?

(This is all actually true.)
