There is a part of human nature compelled to test our own limits. But what happens when this part comes to define us?

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 giving up. What stayed constant was the need to push their boundaries.

Everything Harder Than Everyone Else follows people doing the things that most couldn't, wouldn't or shouldn't. By delving into their extreme behaviour, there's a lot that us mere mortals can learn about the human condition.

There's the neuroscientist violating his brain to override his disgust response. The athlete using childhood adversity as grist for the mill. The wrestler turning restlessness into curated ultraviolence. The architect hanging from hooks in her flesh, to better get out of her head. The performance artist seeking erasure by torturing his body. The BDSM dom helping people flirt with death to feel more alive. The bare-knuckle boxer whose gnarliest opponent is her ego. The dancer who could not separate her identity from her practice until at death's door. The bodybuilder exacting order on a life that was once chaotic. And the porn star-turned-fighter for whom sex and violence are two sides of the same coin.

Their insights lead Jenny on a compulsive, sometimes reckless journey of immersion journalism.
