Danny Wallace I can't believe you just said that

You're not imagining it.

People are getting ruder.

And this is a serious problem.

The book that inspired the iTunes Top Ten podcast 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.

A cry for human decency.

deliciously hilarious.

I politely encourage you to read this book.

Immediately.

But we decided it just wasn't rude enough.
