Comedian and Writer Kat Sadler joins Al halfway through her lunch to chat about her own sense of happiness and how intrinsically she feels that is linked to her sense of achievement of her own goals. Al gets distracted by some grass outside the window for a while and they ponder what role our evolution has to play in our day to day decision making and experiences.
