In this week's show, Jo Stanley looks into the healing powers of the Australian bush, and social scientist Ali Walker explains why you need to stop being a people pleaser. Zoe Bingley-Pullin introduces us to the new super food on the block, hemp, and explains why it will give your taste buds a natural high. Relationship and intimacy expert Dr Nikki Goldstein tells the team why being selfish is good for your relationship, and naturopath Dr David Jivan gives us the scoop on adrenal fatigue – and why it may explain why you're not sleeping. And in House Heroes, we meet a courageous little girl who's been named the first junior ambassador for the Humpty Dumpty Foundation.
