You can change where you live, your hairstyle, the kind of music you listen to, your job, your spouse. But you can't ever really change which team you support.* Dr Damien Pearse is a level-headed man. A clinical psychologist, he spends his days encouraging patients to adopt a calmer, more grounded approach to life. And yet on match days all this unravels. He becomes anxious, panicked, sometimes belligerent, and if things go well for Wolves, manically ecstatic. And he is not alone - wander through any British town centre on a Saturday night and watch as the aftershocks of wins and losses spill out into the real world. Football means so much to so many.

Pearse meets with superfans, scientists, players and trolls, uncovering what drives our unwavering obsession with football. Examining ideas of identity, belonging, shame, modern masculinity and the most extreme acts of football fanaticism, Till I Die offers a poignant reappraisal of an enduring national pastime and passion. *Unless you can stomach being branded a traitor for the rest of your life.
