Ron Kastner experienced what he called a "mortality moment" in his late 50s. A new dad, with two young daughters, it was a "profound realization" that he was entering the third act of his life and that to make the most of it, he had to make significant changes. A businessman who drank too much and was challenged by the stresses of the corporate world, Ron embarked on a journey to discover the life he wanted to live. He embraced new practices for health and longevity and discovered that it was possible to be fitter, stronger, more energetic, more grounded and happier than ever before. Now in his mid 70s, he says: "The feeling of being alive is just so visceral and so joyous....the wonder, that is our bodies, is just like a ceaseless source of amazement for me."Ron shares his story in the book, A Life Yet to Live: Finding Health, Vitality and Joy. In this interview he reveals the backstory to his transformation - becoming a father at an older age, significant lifestyle changes, such as exercising regularly, adopting a healthier diet, abstaining from alcohol, and an holistic approach to longevity that encompasses both physical and emotional health. Read a transcript:  LLAMA podcast website-Affiliation disclosure: This podcast receives a small commission when you use the code LLAMA for purchases from companies below which support our mission.   It helps to cover production costs and ensures that our interviews, sharing information about human longevity, remain free for all to listen. -Hampton FitnessMovement & resistance training have long been associated with living a long, healthy life - along with a balanced diet and good sleep.
