Alongside handball, Casper has studied. Not as a backup plan - he doesn't like that framing - but out of genuine curiosity about the world beyond the lines of a court. He has sat in lectures still carrying the tiredness of morning training in his legs. He has written papers and prepared for exams during weeks when matches were coming every few days.
It hasn't always been easy to hold both worlds at once. But he speaks about his studies not as a burden, but as a kind of breathing room - a space where he is not defined by last night's result, where success and failure look entirely different.
Where the questions are bigger, and slower, and more patient.
Because he has always understood, perhaps better than most, that the game will one day be over. What you build inside yourself - the discipline, the resilience, the ability to show up even when no one is watching - that stays.
