The comedian, writer and mental health campaigner previously brought her autobiographical play Losing It to London's Menier Chocolate Factory in 2011, which subsequently transferred to the West End's Duchess Theatre.

According to press materials, the new show will help us understand why we sabotage our own sanity and provides a manual on how to survive the 21st century, using Ruby’s knowledge from her recent Master’s Degree — in mindfulness-based cognitive therapy at Oxford University — spiked with comedy.

In a press statement, she said, "We are not equipped for this century, it's too hard, too fast, and too full of fear; we just don’t have the bandwidth. Our brains can't take so much information in a world where we’re bombarded by bad news and force-fed information. I can just about take in the weather then I'm exhausted. You open a newspaper, everyone's dead. We’re only supposed to know what our neighbour is up to; if the woman next door to you is having sex with the man next door to her we need to know; but four doors down and it’s none of our business."

In the show, she gives a tour of the brain and how to tame it: "We know so much about how the world works - but so little about our how our own minds work. It’s like having a Ferrari on top of your head but no one gave you the keys."

It is directed by Joanna Bowen, and is produced by Lakin McCarthy Entertainment. To book tickets, contact the box office on 0844 264 2140 or visit  www.stjamestheatre.co.uk.
