It was a summer evening in 2014, when four men barged into Paul Kohler’s family home and began a savage assault on him. They believed erroneously that he had a large amount of money hidden there. The speed of the police response meant that Paul was saved from almost certain death, and the four men were later arrested, charged and imprisoned. Although he felt vindicated by the sentencing, Paul’s worldview was changed forever when he and his family were invited to visit one of the attackers in prison, as part of a Restorative Justice scheme. In an episode recorded in front of a live audience at the Hay Literary Festival, Paul tells Dr Sian Williams about that Life Changing confrontation, and how frustration with the way his ordeal was reported led to him into politics.

His daughter Angie was just five years old - and the news of his death was one of her first memories.

Angie inherited a treasured box of old letters and photographs from her father, but felt unable to open it. Angie wrote in to Life Changing to tell Dr Sian Williams how a decision to mark his life, on the 50th anniversary of his death, helped her finally know her father and understand her part in his life.Producer: Tom Alban

On the threshold of the first COVID lockdown when people were preparing for the unknown, a mother of two young children from Leeds was given a Life Changing diagnosis. Tanja Bage had always been a keen singer and performer and so was increasingly aware of her shortness of breath. There had been several attempts to deal with it, but nothing worked. Eventually she had an appointment with an Ear, Nose and Throat specialist. The diagnosis was cancer, which required almost immediate surgery to remove the tumour, and with it her vocal chords. She would be losing her voice, and she had just a week to prepare herself and her family. Tanja describes that pre-Covid frenzy, the support she received and the challenges of being a mother while having to re-learn how to speak using a Stoma in her neck. Her mix of passion and stoicism meant that not only did she recover after the massively intrusive operation, but she is now involved in artistic ventures with the Laryngectomy choir and the Sound Voice project as well as being a brilliant mother to her children.Producer: Tom Alban

Have you ever locked eyes with a stranger and wondered, "What’s their story?" Step into someone else’s life and expect the unexpected. Extraordinary stories from around the world.

Dan Edozie was brought up by his mother in London, moving between council accommodation and so constantly shifting from one school to another. He didn't know his father. It was a disrupted childhood that would become even more stressful when they tried to settle with Nigerian relatives in the United States. After unsuccessful trips to New York and Boston, mother and son tried a third time to settle in Los Angeles. Dan had just turned 12. Life wasn't easy. They outstayed their Visa leading to a life on the fringes of society. Dan learned how to pan-handle, to beg for money to get extra food. They slept where they could, sometimes on public transport, sometimes in the refuges of the city's infamous Skid Row. Fearing deportation back to the UK they set off at one point for Florida to stay with another distant relative. The journey came to a halt in El Paso when a passport check exposed their illegal status. Before leaving for the UK they returned to LA, continuing their fragile life. Then one day, Dan had an argument with his mother. She had made plans to stay at another refuge a bus journey away. Dan was hungry and although his mother wouldn't stop for him he went ahead and got some food at a nearby refuge centre. When he caught up with her, she was on a bus. Bewildered, he watched as the bus pulled away from a nearby bus stop and headed out of town. Although he had a good idea where she was going, Dan decided to take things into his own hands. He started to look for a place for the night. He was twelve years old, with no ID, no money and only a large black bin-bag containing his clothes. After being turned down by two refuges, a lady at a third started asking all the right questions. How old was he? Why was he on his own? She knew something needed to be done. The next 24 hours saw Dan scooped up by the US authorities. Within days, a foster home was found, and although he and his mother were in contact, a custody hearing went against her and for the first time in his life Dan found the stability he craved. Life was never easy in his new home, but as he puts it 'he looked after business' at school and started to excel as a Basketball player. By the age of 16 he was in the top 50 players of his age group in California. Scholarships followed and eventually he was picked up by one of the top College teams - Iowa State. When he turned professional he decided to return to the UK and played for the Bristol Flyers for six years, before opening his own Basketball training Academy, where young people in the St Paul's area of Bristol get a chance to be inspired by a man who has worked his way up from nothing. The height of his Basketball career came when representing England in the Commonwealth Games.He's still in touch with his mother, and he holds no malice towards her. His focus is on the future and the many things he'd like to achieve. But he looks back on that moment in Los Angeles when a young boy took control of his destiny and in doing so, changed his life forever.Producer: Elaina Boateng
