I had an interesting encounter two days ago with a bloke who had worked for 37 years in hospital administration at a major hospital in an Australian city. He said he was puzzled by all the fuss about the tunnels under the al-Shifa hospital in Gaza. 

He explained that all major hospitals in Australia have elaborate and extensive tunnel systems and networks under their buildings. I asked him why they had these tunnels and he explained in some detail the various roles they played that were essential to a large hospital’s functioning. You can hear his explanation in the ten minute audio clip below.
