A new episode of 'The Nature of Things' titled 'Dad Bods' explores the evolving science of fatherhood, revealing how active involvement in childcare physically changes male brains to increase empathy and significantly lowers testosterone levels (which later rebound but not to pre-fatherhood levels). The documentary highlights the positive outcomes for fathers (longer, healthier lives, stronger marriages) and children (better mental health), and features research from around the globe, promoting the idea of 'kinder men' through fatherhood.
