I'm going to save the song as an MP3 and put it on constant rotation for a week just to get a good feel for it.
This sort of heat it actually record breaking for most parts so it's not often people have to live with it. Thankfully most people/companies are sensible and they work on a cut off policy. Most outside workers would either have not gone to work, or started early. Office workers generally don't have the same issue. There used to be a 100F cut off that schools and businesses closed down at but now the figure is arbitrary and there is no set figure, it's a case by case basis. But the heat is so different depending on where you are. 105+ in Queensland is a humid and heavy heat that makes you sweat a lot and feel shitty. South Australia and Western Australia is a drier heat so you don't feel as hot or as bad at the same temperatures. It gets hot and no one wants to do things however in the Western part of the country it is easier to do things in 100+ weather, but 120 still sucks if your outside.
