When journalist Jenny Valentish wrote Woman of Substances, a book about addiction, she noticed that people who treated drug-taking like an Olympic sport would often hurl themselves into a pursuit like marathon running upon getting sober. What stayed constant was the need to push their boundaries.

Everything Harder Than Everyone Else is about those people willing to do the things that most others couldn’t, wouldn’t or shouldn’t. Throughout the book Jenny speaks with people who push their bodies further than they should go, ultrarunners, bodybuilders, pornstars & prowrestlers. All of which seem to have this one thing in common, all the while taking her own journey into the world of the Muay Thai ring.
