A brass band, goulash cooking in giant pots over open flames, people dancing around a bonfire — a pan-European picnic at the border between Hungary and Austria in 1989 was the beginning of the end of the Cold War. Suddenly hundreds of East Germans stormed the border into the West and freedom. It's a moment in history where the power of ordinary people changed the world.

An Escape to Freedom and the Collapse of the Iron Curtain was presented at the Adelaide Writers' Week

It's Team Wellness Warriors versus Team Medical Miracles. Hear the arguments and you decide! The wellness industry is booming. It's worth billions and its influencers are all over social media spruiking miracle pills and mystery remedies, crystal healing and cancer cures. Some are even steaming their vaginas (hellooooo Gywneth Paltrow!). Have they done the research that mainstream medicine refuses to? Is your doctor really the best person to help you be the healthiest you can be? Or ... are many wellness influencers shysters and swindlers, selling hoax cures, making unproven claims, and putting your bank balance and your health at serious risk?
