What if we told you the Sahara Desert — the largest hot desert on Earth — wasn’t always a sea of sand?

In this fascinating episode of Did You Know with Brent, we travel back thousands of years to uncover a lost world where the Sahara was lush, green, and full of life.

Here’s what you’ll discover:


The Green Sahara Period — How shifting Earth orbits transformed the desert into grasslands, rivers, and lakes


 Wildlife in the desert — Hippos, crocodiles, elephants and thriving ecosystems where dunes now stand


 Early human civilisation — Rock art and archaeological evidence revealing ancient communities living in what is now barren wasteland

If you think deserts are permanent, think again.

Did You Know with Brent? — When the Sahara Was Green

Does your dog wait by the door at the exact same minute every afternoon, or does your cat demand breakfast before your alarm even goes off? 

If you've ever felt like your pet has a built-in atomic clock, you're not imagining things. Dave is joined by resident vet Dr Andrew Cornwell, owner of the Cardiff and Cameron Park veterinary hospitals.

We look at why pets are total creatures of habit, how strict routines keep them happy and healthy, and share a hilarious look at pets who take morning wake-up calls to an entirely new level!


The Science of Habit: How dogs and cats track time using environmental cues like light changes, sounds, and scent trails rather than clocks.


Emotional Security: Why predictable routines minimize anxiety and stress, helping pets feel safe and confident.


Behavioral Benefits: How consistent feeding, exercise, and sleep schedules prevent boredom and destructive habits.


The Morning Clock: Why pets master our schedules so well and how to gently adjust their wake-up routines without breaking their trust.

If you want to understand your furry friend better and keep them happy and healthy, this is the deep dive you need.

Why Pets Thrive on Routine with Dr Andrew Cornwell

With half a million Australians now using or trying popular GLP-1 weight-loss and diabetes medications, the way we think about appetite and health is undergoing a massive shift. 

Private prescriptions are soaring, out-of-pocket costs are hitting hundreds of dollars a month, and this revolution is doing more than changing waistlines—it’s completely reshaping the food industry. Dave is joined by Registered Nutritionist Dr Emma Beckett for our weekly segment Nutrition Decoded to break down the GLP-1 boom and explore whether everyday food really can act as your medicine.


The Massive GLP-1 Surge: How monthly usage skyrocketed to 500,000 Australians, with private prescriptions driving nearly 44% of total use.


The Cost Barrier: Examining the equity challenges as private users pay between $200 and $700 out of pocket each month.


Reshaping the Supermarket: Why food manufacturers are racing to design high-protein, nutrient-dense, portion-controlled products to match changing consumer appetites.


Can Food Be Your Medicine?: How proteins, healthy fats, and fermentable fibres naturally trigger your body to release its own GLP-1 hormones.


Biology vs. Behaviour: Why lifestyle and genetics mean changing your diet isn't always as simple as "eating less."

If you want to understand the science behind the headlines and how food science is evolving, this is the deep dive you need.

Nutrition Decoded – The GLP-1 Boom, Food Innovation, and Can Food Be Your Medicine?

Have you ever caught yourself walking past someone sleeping rough and looked away, not knowing what to say or fearing you might make them uncomfortable? 

Marking National Homelessness Week, new research reveals that nearly a third of Australians admit to doing just that—even though deep down, nearly 80% of us want to help. In this episode, Dave is joined by Nic Marchesi, Co-Founder of Orange Sky, 2016 Young Australian of the Year, and 2020 OAM recipient.

We discuss why human connection is just as vital as a hot meal or a clean set of clothes, and how a simple acknowledgement can completely change a life.


The Look-Away Habit: Why nearly 1 in 3 Australians admit to walking past someone experiencing homelessness without acknowledging them.


The Fear of Getting It Wrong: How to overcome the anxiety that stops 79% of people from reaching out to someone doing it tough.


More Than Just Laundry: Why Orange Sky discovered early on that the real magic happens on the chairs alongside the machines through non-judgmental conversation.


A Public Health Priority: Why the community agrees that chronic loneliness and social isolation must be treated as a major national crisis.

If you want to move past the awkwardness and learn how a simple hello can restore someone's dignity, this is the deep dive you need.
