Did you know that even one rude comment in a life and death situation can decrease a surgeon's performance by as much as 50%? That we say we don't want rude politicians, but we vote for them anyway? Or that rude language can sway a jury in a criminal case?

Bestselling writer and broadcaster Danny Wallace (Yes Man, Awkward Situations For Men), is on a mission to understand where we have gone wrong. He travels the world interviewing neuroscientists, psychologists, NASA scientists, barristers, bin men, and bellboys. He joins a Radical Honesty group in Germany, talks to drivers about road rage in LA, and confronts his own online troll in a pub.

And in doing so, he uncovers the latest thinking about how we behave, how rudeness, once unleashed, can spread like a virus - and how even one flippant remark can snowball into disaster.

As insightful and enthralling as it is highly entertaining, F*** You Very Much* is an eye-opening exploration into the worst side of human behaviour.
