Dr Rudy Brasch, with his wife Li by his side, made it his life's work to track down the meanings and origins of words and phrases, myths and customs. How Did It Begin? investigates courtesies and customs, the manners and rituals that are integral parts of particular careers and the seemingly odd traditions that surround our sports and festivals.
