The Happy Pod: Saving lives with the man who saved mine

Available for over a year

Mesfin Dollar, who grew up in rural Ethiopia, had to travel to the US for two heart surgeries as a teenager. Twenty-five years later, by chance, he was reunited with the surgeon who saved his life -- when they both volunteered for a charity mission to his home country. Mesfin and Dr Jim Kauten went on to work together, performing hundreds of life-saving operations. Also, a Paralympic athlete and musician who is blind talks of his joy at being sent a specially designed amplifier. It is thought to be the first to include braille on the controls, giving Anthony Ferraro the freedom to adjust the sound of his guitar himself. How farmers in rural Malawi are getting help and advice from Articial Intelligence through a new chatbot. Why a cow in Austria has found fame for using a broom to scratch her back, suggesting cattle are far more intelligent than we think. Plus, a woman who has entered the male-dominated world of lorry driving in her 50s, and a girl who joined her father's photography business at the age of nine.
