Temperatures in the outback of Australia have been known to reach up to 57 degrees Celsius. That’s over 130 degrees Fahrenheit. It’s unbearably hot. And the search-and-rescue guys say if someone is dropped into the middle of that, with nothing, no water, within three hours, they’d be dead. And the most important part of you to keep cool is your head.

You have to reduce the risk of overheating. You could use your T-shirt, but then the sun would sear your body. So if you are a guy, all you’ve got left are your boxer shorts. Hat on, some sort of protection. I’m ready to go. Your head is the most vulnerable part of your body and your hat will keep you cooler. But the big problem will be water. You might need to resort to extreme measures to survive. The only thing I can do is to drink my own pee.

I’m in the Kimberley in north Australia. I’m showing how to survive in this hostile wilderness. You’ll need water, but if there isn’t any, you can drink your own pee. And this is something I’ve never done before and I’m expecting it to be pretty horrible. But I need to keep those fluids going in. It may seem disgusting, but your own urine is safe to drink.

And if I just peed on the ground, that’s all those fluids wasted.

God. There’s no getting away from it. That really is pretty horrible. It’s like warm and it’s salty and not my favourite.
