 This is Radio EcoShock. I'm Alex Smith with Dr. Liz Hanna from Australian National University. She is a specialist in how the human body handles extreme heat. And as you point out, there have been studies done for the military and also for athletes, how they're going to cope, say, in the Summer Olympics. But it seems like we haven't done much about the miners, the farmers, or the people who keep our whole system going. What does need to be done? I think we need a new mindset.
